Allegedly of course.
Jony Ive basically works for Open AI (it's more complicated, but it's a good approximation), and has more or less rebuilt a designing team over there.
He's not the central person mentioned in Apple's accusations but that's arguably the central point that's triggering all of this.
He "took" several Apple employees with him when he left and there's been a steady stream of Apple employees going to OpenAI.
Ive isn’t responsible for all of them obviously, but the articles about lawsuits says there are 400 former Apple employees at OpenAI.
I wouldn't say 4 is lots. The entire list is massive. I haven't counted myself, but someone claimed that macOS 26.6 has the all-time record with 155 CVEs.
edit: it seems asking for a source it frowned uppon in this site. And it seems there's no source.
That would be a very Apple thing to do.
And it seems nobody has a source so it's just humors as usual.
That's something Steve Jobs would have done.
