With that attitude I ain't implementing special hacky workarounds for Safari anymore /s but in all seriousness why? barring developers with malicious intent most developers would just want cross-platform tooling, open systems and less friction in making apps all of which modern web provides and with PWA the experience is even more pleasant as long as relevant API's are available. But when you have a single browser engine preventing this experience it's simply not right. I don't want to code my app twice especially since I don't need the native performance.
You're painting with an awfully wide brush there. Apple is screwing everyone, but especially developers who want to develop truly free/transparent apps without ads, tracking, or other predatory monetization models (i.e. the "good" ones).
