Dont forget what kicked this age verification in first place. Initially they wanted do age verification for porn, and only year later they moved into social media seeing there's wasn't huge pushback.

First they banned the children from smoking cigarettes, and I did not speak out, for I was not a cigarette. Then they came for the murderers and pedophiles, and I did not speak out, for I was not a murderer or pedophile. Then they came for the carjackers, and I did not speak out, for I was not a carjacker. Then they came for the people who said "Free Gaza!", and there was no one left to speak for me.
This is famously why ID checks at the liquor store led to the government eventually requiring a mandatory ID check anytime you walk the dog or go to the beach... except none of that happened.
So even if this change doesn't affect you right now, but it will affect you later then it'll be too late to fight agaisnt.
