Well, for a $200 app that was feature complete when I bought it, I am not at all sure what I'd want them to do with it. It'd be a really hard sell to go from almost a decade of "free and professional" to a subscription model- I'd much rather have them just keep maintaining the software exactly as is so I can use it when I buy my next MBP in 2026.

So I am a bit skeptical that your prediction is accurate. But I can't tell the future and I don't know folks at Apple so maybe you know something I don't.
