Pi-hole is such a great tool. I've been running it for a few years on a raspberry pi zero, and am constantly astonished by the sheer amount of cruft it blocks for me.

I have had many times click an article link on reddit where everyone in the post comments complains about how the site is riddled with ads that it makes it unreadable and all I see is the article with a lot of whitespace.
IT department does not like that, but I had them install Firefox on the machines of my team, so we can install uBlock Origin. People are _amazed_ how the internet does look without ads.
On the pihole subreddit there's a wiki with lists of domains you can whitelist for certain services. I had to whitelist something for xbox live to work.
