There is only one way out: noscript/basic (x)html browsers which does not require the army of devs from google or apple. Regulate aggressively (or it won't happen) to make at least critical web sites work with them (administration online services, utility online services, shopping, banks). You can do wonders with basic HTML forms.
video streaming services would just need to support the <video> element with a URL where seeking is standardized (I think apple HLS did just that).
