I'm all-in for blocking ads, but I've found full-OS ad-blockers to be entirely unnecessary - I simply don't use apps with ads.
The few apps with ads that I sometimes can't avoid aren't fixable by ad-blockers. (e.g. ads in Google Maps)

I don't use any apps with ads, but Blokada has reported blocking ~100k requests a week on my phone.
