If they haven't actually kept any changes, then they haven't fooled you in 2023. You can argue that they tried and failed - or that they f*cked up. But as they are returning to that commitment and reverting their recent changes to align with their original promises, using the "fool me once" claim seems totally off.
Except they didn't walk everything back; they only walked back the biggest stuff -- retroactive license changes and the likely illegal clauses that could put someone in debt. The royalty+subscription format that they promised they'd never employ is still very much in evidence, as are other things they previously promised they'd never do.
And the transparency stuff and multi-license shuffle might be re-set now, but starting in 2019 it was being manipulated in a long play that continued right up until someone noticed and called them on it.
Which means you know that in the future they'll continue to do whatever they can do without getting caught, and then walk back the bits that people are MOST upset about while keeping the stuff that's both legal and not drawing a lot of attention.
