Genuine question: what would it take for a lot of indie mobile developers to move to the web? It seems app stores are pretty punishing with their capricious rules and high fees, and the web avoids that with greater freedom, better backwards compatibility, and lower fees. Some of the tech was flaky 10 years ago, but a lot of web tech is impressive now, and still advancing (e.g. WebGPU and CSS container queries). I guess discoverability and monetization are key points, but what about free art projects or small games built as side-projects and such? It seems to me they wouldn't have much to lose and a lot to gain by moving to the web.
