> Kimi will train their models on your interactions

I find these kinds of concerns increasingly silly: most of the input to these models will be ... previous output from the very same models, alongside the occasional half-assed human command to fix something and "make zero mistakes". Who cares if they train on that? Let them, if it makes their future models better!

99% of users are not working on any special IP to worry about that.

Indeed, the B2B / no-data-retention market is still going to provide plenty of business for American companies even if every hobbyist uses open-weight models.

Exactly; this is a no-go for me, I will wait for an independent provider to sell the service, which is possible thanks to the open weights.
