Why are some trackers exempt?

[everypizza1]

I was going to try out this browser, and I linked it in a Matrix chat. Someone pointed out that some trackers are exempt from tracker protection. Here's where it's happening:

desktop/src/browser/app/profile/better-fox.js

Line 61 in 1a450eb

pref("urlclassifier.features.socialtracking.skipURLs", "*.instagram.com, *.twitter.com, *.twimg.com");

There are also some more exempt from it here:

desktop/src/browser/app/profile/better-fox.js

Line 60 in 1a450eb

pref("urlclassifier.trackingSkipURLs", "*.reddit.com, *.twitter.com, *.twimg.com, *.tiktok.com");

Why is this?
