After that point it's been becoming more and more sterilized. My web apps that automatically played some sound aren't going to work anymore without some obnoxious "click here to begin" screen that doesn't fit in with the content. No more plugins letting us extend our browsers in new ways (what a convenient "coincidence" for Google that this gives them more control over what the user gets to do and makes tracking what goes on easier). I have to give Reddit Enhancement Suite permission every single time it tries to show a preview from a domain it hasn't previously done so from before. It's all suffocating. HTML5 makes up for some of the lost capability but it's not enough and what parts of HTML5 are going to actually work are basically at the whim of Google now.
But at least HTTP/3 will let us load buzzfeed listicles a few milliseconds faster, so there's that.
