Before Elon Musk's takeover of the social media platform last year, Twitter signed a multi-year contract with Google related to fighting spam and protecting accounts, among other things, the report said.
Sounds like it's not about hosting their infrastructure but tangential services.
Of course Elon Musk thinks he can anti-spam and protect accounts better by himself and without external cost.
I'd love to see cloud hosters refusing to work with Elon Musk because of all the unpaid bills stuff.
