I do the same (uBlock Origin) and almost every site works, but there are a still a few I need to whitelist because they do weird stuff, like triggering their own scripts to run from analytics callbacks. Airline and banking websites are a couple of common categories of sites I usually need to whitelist to work properly - that's not really an issue though as they don't usually have 3rd party ads.

Yeah I have a clean backup browser for the few sites that don't work and I still want to use. I'm always reminded how CRAP the internet has become.

I block everything too and sites break so rarely that it takes me a while to link the breakage with blocking of trackers.

I do the same thing too, blocking all 3rd-party junk using uBlock Origin. As one specific example, I've had to let motortrendondemand.com fire off Omniture, because apparently their video player (through Kaltura) depends on it.

It's just lazy design, or possibly malicious, I'm not sure.
