It’s as weaselly as the wording where they say things like “we use your data to improve our services, eg. personalised advertising. To opt out of personalised advertising […]”

Nowhere does it say they stop using your data.

And it states something very obvious that you seem to have overlooked:

""Google Photos doesn't sell your photos, videos, or personal information..."

This says that they "don't", it very clearly does not say they " won't".

It feels just as weaselly to me when, by use of confidence-inspiring “plain language,” firms manage to pass off the impression that they’re making Solemn Categorical Pledges foreswearing the bad behavior that made users nervous—while preserving almost entirely the substance of the bad behavior.

Google seems especially invested in that kind of stunt. Remember their “ad privacy” consent screens for Chrome—which, ridiculously, framed consent to additional tracking as a “privacy” measure? (https://news.ycombinator.com/item?id=37427227; Aug 2023 / 974 points / 557 comments)
