To interject with a potentially inconvenient fact, I think the premise that ad blocking (request blocking) is now obstructed, is incorrect. Therefore this response seems exaggerated to me.

This is because Chrome extensions can use the 'debugger' API to send remote debugging protocol commands to a page, to intercept and filter / block all requests.

There is no need to use the provided Chrome extension APIs for blocking. Google can remove all of them, I think, without effect.

This is because there are multiple ways to do the same thing. Authors/engineers complaining that now they are impeded, are in fact mistaken.

Disclosure: I know this because I have actually re-implemented the blocking from AdBlock Fast using CRDP Network domain.
