Companies can be damaging and anti competitive even if they aren’t total monopolies. Being an oligopoly or having a significant portion of market share is enough. Keep in mind many of these companies have more users than most national governments do - and they have soft power on a similar scale. Another angle is network effects - social media companies face reduced competition due to this and so they too should be regulated above a certain size since there isn’t enough competition or choice there, because the value of access to those particular platforms is very high due to their size. > Even with banks, if one bank rejects me, I can (hypothetically) go to another one down the street. What if they all reject you though? For example what if all banks decide they are better off debanking someone to stay in the good side of politicians who might punish them otherwise (like via regulation)? Some of these services are fundamental and should be forced to provide service no matter what.
