I minored in business law and read them. It terrifies me what people agree to without reading... McDonald's, TikTok, and snapchat just added clauses to their terms of service that say users are not allowed to participate in Class Action Lawsuits. Unfortunately the Supreme Court was swayed by AT&T in 2019 so now every business is doing this so they can't get sued by groups, just individuals who they KNOW can't afford to hire a lawyer and fight.

They have to allow an opt out option, though, so always Control F and find the class action and opt out section to make sure you don't get screwed out of your rights.
