I personally just don't believe in subscriptions for apps. I'd rather just pay a fair amount up front. Especially since my usage patterns aren't consistent (I may not use something for a good while but return to it later). Perpetual licenses are why I own such a large library of paid apps and why I'm okay with paying even if I might not really maximize my use of it today. It's also why my Steam library is filled with games I don't play... 😅.
