Platforms are good for the platform's founders and investors and they take care of the transaction cost and do provide some marketing although I often find platforms limit my choice instead of expanding it.
I don't mind the existence of platforms if they don't have exclusivity on content. But I would love an alternative, where you could pay content creators 2, 5, 10, 20 or a few hundred cents directly.
I can chat, phone or email anyone directly for free or almost for free, even with advanced security. Why can't I pay them for free or low cost? Isn't the tech involved in sending or receiving a secure email with attachement more advanced than the tech that makes sure one bank credits the same amount someone else's bank debits?
