> Not sure if you’ve intentionally omitted it but I would also include YouTube in this list

Yeah I did conciously omit it actually, but only because I consider Youtube to be basic internet infrastructure and quite valuable if used right.

However, for me personally, I've actually blocked Youtube from Chrome when not in incognito mode to keep me signed out by default and I've also completely blocked the site from my iPad (and ofc I also don't have the app installed).

I unfortunately struggle with some form of social media addiction and I've made pretty dramatic changes to keep myself away from these sites.
