GitHub Sponsors Passes $100 Million as Sony Music Sues Udio Over 30,000 Songs
Two stories about compensating the people whose work underlies modern software and AI surfaced the same day, and they represent almost opposite mechanisms for solving the same problem. GitHub says individuals and organizations have invested more than $100 million in open source maintainers and projects through GitHub Sponsors since 2019, with $10 million of that total arriving in just the past five months. Separately, Sony Music has filed a second copyright suit against Udio, alleging the AI music company copied 30,117 recordings without permission to train its models.
The Voluntary Model
GitHub Sponsors is opt-in on every side: maintainers choose to make themselves sponsorable, and sponsors choose to pay, with no legal obligation connecting the two. That the run rate has accelerated — $10 million in five months against $100 million cumulative since 2019 — suggests the mechanism is compounding rather than plateauing, likely helped along by the fact that AI coding tools and AI companies training on public code have made the dependency on open source infrastructure more visible, not less. Voluntary sponsorship works because the payer and the beneficiary are usually in the same ecosystem: a company that depends on an open source library has a direct, visible incentive to keep its maintainer funded.
The Litigated Model
The Udio suit is what happens when that same underlying dynamic — a company’s product depending on someone else’s created work — has no voluntary mechanism attached to it at all. Sony’s specific figure, 30,117 recordings, is doing a lot of work in this filing: it moves the case from a general accusation about training practices to a specific, countable claim of unauthorized use, consistent with the structure of the first suit Sony filed against Udio. Where an open source maintainer can choose to enable sponsorship and a company can choose to pay it, a record label has no equivalent mechanism to opt a catalog into paid AI training use after the fact — litigation is the only lever available once the training has already happened without a license.
Two Industries, One Underlying Question
Both stories are ultimately about the same question: when a piece of software or a media catalog becomes an input that other products depend on or are trained on, who gets paid, and through what mechanism? Open source has spent years building voluntary infrastructure — sponsorship platforms, foundations, corporate matching — to answer that question without lawsuits. The music industry, facing the same question from AI training specifically, is answering it through the courts instead, one countable catalog at a time. The gap between $100 million in voluntary sponsorship and a lawsuit counting 30,117 individual recordings is really a gap in what kind of compensation infrastructure existed before AI made the question urgent.
