IDK if WordPress plugins respect SEMVER, but shouldn't this auto-update thingy update only patch versions, or minor versions at most? Idk, breaking changes like these is definitely not something you want your CMS to do overnight when you won't notice until you receive complaints that your site is broken
Yes and that is a huge deal - I made this point to others that it shouldn't be considered a minor version change
When you roll out an auto-updates mechanism you're saying to the people who enable it "you can trust us to do the right thing with your project while you are elsewhere -- this is a risk but it's one we manage for your benefit".
If you roll out a change for purely political/commercial reasons that are ultimately not your end user's concern -- we're not a party to that lawsuit -- then you're undermining the trust in that mechanism entirely.
It was a stupid, arrogant, underhanded thing to do.
