I’d even specify that. Loosing uBlock Origin on Firefox is like getting rid of the web per se.

Pretty much, and I think this highlights just how important it is to have at least two independently developed browser engines. If Chromium becomes the only game in town that would effectively let Google, which makes most of its revenue from ads, decide how we access the internet. That would be an absolutely terrible scenario to be in.

I just went to a website that gave me a full page ad with no X button to close out of it.

Hell no. Shit is going to get so bad if they remove ad-blockers. Fastest way to kill their user-base.
