We need a change in anti-trust law given how many markets are now dominated by network effects. Any company that controls more than (some) percent of a significant (by some definition) market/medium/distribution channel loses the ability to unilaterally ban/refuse to serve a user except for VERY limited reasons, such as non-payment, intentional vandalism, fraud, or other criminal (not company policy-violating but actual law-breaking) activity. If such serious violation is alleged, account can be suspended pending ruling by regulatory agency. If reg agency rules that no such violation took place, the suspension will be ordered lifted and a fine imposed as compensation--no lawsuit by MomsBasementStartup against WeOwnYouMegaCorp is necessary. So, if you really want to have the power to ban whoever you want for whatever "terms of service" reasons please you, better make sure you never grow very big. Your ability to reject users falls as their ability to reject you and go with your competitors falls.
