AI labs are limited by the available training data, the best way to improve model performance is more and better training data.

The AI labs and the downstream companies that sell training data to them vacuum up everything they can.

Illegal residential proxies (botnets) that once have been used by hackers and scammers are now used to vacuum up the Internet.

They are now vacuuming up antique books that are practically useless.[1]

In face of this is is unthinkable to me that they are not training on API data.

The loss of trust is already here.

I know of one German company that uses AI only in areas where they have to compete with (foreign) startups. For their core business and everything else they are waiting for an on-prem solution. Apparently Microsoft can provide on-prem GPT-5.
