Even if it were slightly more expensive, it's still a better sales proposition for a company if they can run it from a hardware provider with their own locked down VPS and ensure that their IP is protected and that their data isn't being stolen or trained on. The fact that it's a little cheaper is icing on the cake.

Honestly, it's the only sane way for the market to move. The big labs are obviously stealing our data. Anthropic in particular clean-rooms everything you feed it, even if you opt out, so that it can train on your IP without getting sued. It's a copyright grey area they're abusing because the law has not kept up.
