I mean, as I said, that's ToS boilerplate. Go look at practically any service you subscribe to or even thought of subscribing to. There will be very similar verbiage there.
I'm sure Facebook had some pretty good boilerplate (probably something even more strongly worded and custom) and that didn't stop them from being GDPR slapped.
We have had this or similar wording for decades now. It has been vetted by many thousands of lawyers at this point. I highly doubt it’s as unenforceable as you’re trying to paint it out to be.
