Ads are lifeblood of social networks, if no ads then they have to find some other ways to make money. Taking into account that a few people are ready to pay for using social networks, this may not be a good venture model. Although, I might consider paying for not seeing ads:)
Paying for YouTube premium is easily one of my best expenses. I use FB and IG less and less because they’re increasingly a dumpster fire of annoying ads.
