I think there will be two webs if this goes through.
One corporate web filled with surveillance, ads, forced use of approved operating systems and software, no ad blockers etc. This is the one all people who don’t care will use.
Then you will have another web where servers do not implement this shit. You are free to use any operating system, plugins, etc. The servers will be run by individuals. It’s the corporate free web that many of us actually want. It will have stuff like Lemmy and Mastadon, and probably some kind of a web search since the main search engines will all not be here I assume. New software technologies will evolve here.
As long as they don’t put this shit on router and network level, it’s possible to escape it by not using the ordinary web. But ofc we will have to use it to some degree at work, probably.
