I really do not understand this comment. Even if somebody works in big tech, what is wrong with that? Where should I work? Would that change anything? Can't I criticize big tech, if I work for one? Can't I try to change big tech from inside? Next: What wrong with "criticizing small players"? I do not have to worry about their bills. This is not my business, it is theirs. They have their own business models, these are their bills. Maybe they have incorrectly positioned their business plan? Do not play victim the card here. It is right that mega corporations were created using our hands, but it was not our decision. Most people do not know what they are doing "using services", but you cannot blame people for using big tech, if there is really nothing else that matters. We may be forced to use some solutions, but it does not have to close our mouths!
