If they cared they would invest time and resources into building that platform on top of nostr. Content creators should pay the devs to build them the tools they need. The arguments are completely upside down.

They do care and they do pay devs to create CLOSED solutions. This means they don’t know about nostr because you could pay a dev just the same to do it on nostr.
That could also mean that they just want to protect demselfes, but do not care about censorship resistance for others. But I agree with you that they should do that, I to not understand nostr:npub1lelkh3hhxw9hdwlcpk6q9t0xt9f7yze0y0nxazvzqjmre3p98x3sthkvyz complaint that someone else has to build that for them. Who better to build those tools then content creators themselve?
