hmmm actually I think parent does have a point seeing that we are seeing more weaponization of platforms the past few years. Say you have a specific view of reality that differs politically or labelled to be reflecting "propaganda" of specific states, interest groups, political spectrum.
Then yeah AWS or any US stock exchange listed, centralized cloud host would be deemed a platform risk but for majority of us it is not an issue.
Nevertheless I am cognizant of the political risks translating into various platform/financial issues for such groups but it's always been this way when new mediums of information exchange are introduced. Perhaps a short time during the early days of the internet such idea was a reality but we've gone far past that, regulators and political interests have caught on and it would take a very robust , decentralized and scalable mesh network to pull it off successfully.
