The Open Source Pledge: What it does and why it matters for Open Source Software?

Open source software (OSS) runs the digital world. Maintainers work hard but often get no pay. Companies earn billions—$8.8 trillion yearly, says Harvard—from their efforts. The Sentry Open Source Pledge, started by Sentry asks firms to give $2,000 per developer each year to help maintainers. It’s a big step, but other options exist. Tidelift offers subscriptions. License-Token.com uses NFT tokenized code and NFT licenses. Gitcoin funds open source through votes. Drips Network sends small, steady payments. OSS flaws like Log4Shell show why funding matters. This article looks at the Pledge’s design, effects, and limits. It compares alternatives to find better ways to support OSS.

Introduction

The Sentry Open Source Pledge began on October 8, 2024. Sentry and partners lead it. It pushes companies to pay $2,000 per full-time developer yearly for OSS maintainers. OSS is key to tech, says the Open Source Initiative (OSI). Yet, maintainers often lack funds, facing burnout and risks. The Pledge aims to fix this. This article studies its start, rules, money impact, legal issues, and weaknesses. It compares it to Tidelift and License-Token.com. It also checks exploitation and lists supporting groups.

Historical Background

The Sentry Open Source Pledge grew from Sentry’s efforts to support OSS. It moved from matching donations to a bigger plan. The Open Source Initiative (OSI) backs it. It reacts to problems like the XZ Utils backdoor and Log4Shell vulnerability. These show maintainers need money.

Participation Mechanics

Companies join the Pledge in steps:

Payments go through Open Collective. Firms renew yearly.

Payment Distribution and Maintainer Transitions

Payments follow use tracked by thanks.dev. Company-owned projects don’t get funds. Money stays if employers join the Pledge. It covers OSI-approved projects, even dual-licensed ones.

Payment Enforcement Mechanisms

The Pledge isn’t forced by law. Firms report payments willingly. If they don’t, they’re cut from opensourcepledge.com. Tools like Ethereum smart contracts could help enforce the monetization of the code.

Problems with Non-Legally Binding Structure

The Sentry Open Source Pledge isn’t mandatory. Companies can skip it with no penalty. This weakens it. Profit-focused firms may ignore it.

Legal Liability of Open Source Developers

OSS developers risk legal trouble worldwide:

• United States: The Digital Millennium Copyright Act (DMCA) and tort law can blame them for flaws like Log4Shell. The Apache License 2.0 says no liability, but courts may still sue.
• European Union: The EU’s General Data Protection Regulation (GDPR) fines up to €20M for data leaks from OSS. The GNU General Public License (GPL) doesn’t shield them.
• Other Regions: India or China may sue for patents or state rules.

The Pledge pays $500–$2,000 yearly. Risks outweigh pay, because the payment of the pedge is not tied to the usage and only a donation. Additive models for licensing would be required, but this is problematic with the open source definition of the OSI, preventing licensing where commercial use needs to be paid.

Bootstrapping Limitations and Exploitation Resistance

The Sentry Open Source Pledge doesn’t help new OSS projects start. It works best for big ones like Django or Flask. Its $2,000 per developer needs companies already using the software. New projects lack this. Compare:

• Tidelift: Needs projects in its list. No help for startups. It fights exploitation with contracts.
• License-Token.com: Helps new projects with tokenized licenses. It ties money to use, cutting exploitation.
• Gitcoin: Funds startups with votes https://gitcoin.co/grants. Pay varies but helps some.

Stephen Walli’s "There is Still No Open Source Business Model" says donations don’t stop exploitation. Companies take $8.8 trillion yearly (Harvard) without giving back. The Pledge struggles here.

External Exploitation and Donation-Based Limitations

Walli notes donations lack demand. Maintainers stay at risk. The Pledge’s $500–$2,000 is small. It doesn’t stop companies from using OSS for free.

Financial Impact and Adoption

By March 2025, 25+ firms gave $2,582,512 via the Sentry Open Source Pledge. This helps ~2,583 maintainers with $500–$2,000 each. It’s 0.4%–1.5% of the U.S. median.

Comparative Analysis of Funding Models

Tidelift Model Exploration and Pricing Comparison

Tidelift:

• Mechanism: Charges $100–$150 per developer yearly. For 100 devs, it’s $10,000–$15,000. Maintainers get $50,000–$100,000.
• Technical Details: The Tidelift CLI checks files. It fits CI/CD with APIs. Pay matches use, tracked by npm.
• Pricing vs. Pledge: Tidelift costs 5–7.5 times more than the Pledge’s $2,000. It pays better but hits firms harder.
• Liability Context: Tidelift cuts risk with SLAs. The Pledge doesn’t.

License-Token.com as a Fairer Alternative

License-Token.com:

• Mechanism: Maintainers sell NFT licenses. Prices are quantfied for the development effort royalty percetage.
• Technical Details: Smart contracts handle royalties.
• Fairness: Beats Tidelift and Pledge. Pay matches use. It fits fair code and fair source software. It’s real monetization.

Challenges and Considerations

• Voluntary Limits: The Pledge can’t grow big.
• Liability Risks: Maintainers face lawsuits for little pay.
• Bootstrapping Gaps: It skips new projects.

Conclusion

The Sentry Open Source Pledge helps big OSS projects. It’s easy but weak for new ones or exploitation. Tidelift pays more but costs more. License-Token.com is fairer with demand-based pay.
