This is a double edged sword. Yes, web technologies are sprawling, but they are also constantly improving, which is not always true of the more tightly controlled platforms. You can build on iOS for example, where there are generally only a few ways to do things. But then you're waiting on Apple to release new stuff.

There will always be platforms that are the Wild West, build-your-own-adventure decentralized toolkits and others that have a narrow political agenda and are more stable. Neither is better, it's just a question of what kind of frustration hurts you less.
