well, we apparently see two different realities.
i do acknowledge that competition exists, but i also argue that this is being overshadowed by big companies who may compete amongst themselves but use their power to prevent competition by smaller companies.
you seem to say it doesn't matter, people wouldn't buy from big companies if their products weren't good. and i disagree with that. people buy from big companies because they are cheaper, because their marketing is overwhelming, and because they are lured with free products that small companies can't afford to offer. creators are forced to be on youtube because the audience is on youtube. competition exists, but it doesn't matter. same goes for publishing books on amazon. i know one author who stated that he can't afford not to be exclusive on amazon because it would significantly reduce his revenue.
besides a few exceptions, small companies can not compete against big ones. it is not a fair playing field.
and i really don't understand why you keep arguing about competition, and claim that i don't acknowledge that competition exists. i didn't make such a claim.
the thing i am claiming is that competition does not counteract centralization.
