With streaming media they created this tiny DRM blob (you might have have heard of widevine.drm) which every browser needs to have to decode certain types of streaming media. Now imagine if something like that would be required ... the website would only be loaded and rendered if the module would "validate" that nothing has been tampered with (think: signing and checksum validations). - Suddenly no more content filtering/adblocking or maybe just enhancing websites with userscripts. That is the web google is trying to create. Totally under their control and static. The user will again just like with television be a receiver without any influence. I personally find this to be a very scary, degrading and sad thought so much ... that i would likely turn my back on this kind of web as much as possible and look for other networks (maybe something like i2p, gemini , ... )
