Checkout "revanced" (the git repo) it contains a collection of "patches" for a lot of major apps. There are AdBlock patches for Instagram and TikTok. You can build the patched APKs on your phone using their manager app
Which is kind of shitty because (also AFAIK) you end up hurting the publishers who run those ads way more than the advertisers who place them or the ad platforms who facilitate buying and selling the ads... I'm pretty sure a lot of ad platforms will ask for their money back if they find out the publishers are serving ads that don't get seen by human eyes.
I don't know how much of that is true, but yes the intention is to cause disruption to ad systems that encourage data profiling and so groups involved from publishers to the auction owners will be distrustful of one another increasingly.
It is a misconception that ad blockers significantly impact the ad market as a whole, obviously they impact Google and web advertisers though.
