Make no mistake, what Google is doing is absolutely dangerous. Malvertisements are definitely a thing. Back in 2010, I got a virus from an ad on a meme site that just went through and trashed my hard drive.
It’s unfortunate that there are use cases out there where Chrome is absolutely required. Firefox can’t display large directories, for instance. It’ll lock up while chromium browsers work fine.
The only example I can think of off the top of my head is something I’ll have to DM you.
