OK i see, re-reading this with your top level post is "not all vulnerabilities are the type that could be bought by (insert state actor)", which makes sense (for some reason I thought you meant that they were buying the type of bugs that would end up getting reported to a BBP, but I just misread the original comment).

And yes the Saudis definitely bought software from NSO Group but it's also been used by plenty of other governments, including half the EU...
