Oracle has also been guilty of locking modern table stakes behind the MySQL Enterprise / Heatwave pay gate, such as vector indexes and JS stored procedures. And while they've recently announced more of this stuff will move to FOSS soon, at the same time their response rate to new bug reports has become worse than ever before, which is deeply worrying.
And a couple days ago Oracle announced that they're nonsensically changing their MySQL versioning/LTS naming yet again. So now the way you identify an LTS is "major version is an even-numbered last two digits of a year, while minor version is exactly 4 to represent LTS releases always being in April." So for example MySQL 28.4 will be LTS, but 28.7 and 28.10 are not. But prior to this, 9.7 and 8.4 are LTS, and 8.0 was de facto LTS but now EOL. It's bizarre. I wish I was joking!
