With this change, extensions can “only” alter/inspect/redirect/block 30,000 domains if they use the webRequest API. That’s not enough to build uBlock Origin with, but at least there’s limit now.

That seems like an arbitrary number.

Remember, politicians don’t pass racist laws by directly saying they are excluding PoC into the law. They do it by targeting commonalities that happen to apply to PoC.

Google isn’t going to flat-out say they are blocking uBlock Origin. They are going to do it by implementing “security features” that just so happen to target only uBlock Origin.
