The major Ai providers (frontier models) have contract clauses and marketing copy that specifically say they do not use your data or sessions for their training.

Microslop / GitHub is a notable deviation here.

Agreed. (Reasonable) humans also don't ask for 20-50% raises year on year, but replacing workers with AI places incredible pricing risk in your business operation. AI may be cheaper in the short term, but the ultimate goal of AI companies is to capture as much value as possible, and they will have no problems pricing AI tooling as close to the replaced human salaries as possible.
