Do you really trust TOS like that, though?

Assuming they're not blatantly violating the policy (which I think they've done before), it's pretty easy to weasel out of that statement by only sharing keywords from the conversation, or only sharing the info with advertisers (but not WhatsApp and Meta), or redefining what a "personal conversation" is, or carefully redefining what "end-to-end encryption" means, or ...

There's no transparency, a huge power imbalance, and terrific pressure on WhatsApp/Meta to monetize as much as possible.
