Nope. Our software is sold directly to end users. Pretty much any major company has software releases with 9 in it. Discord, dragon, play station, android, apple (watchOS 9), I could list more. And since a lot of software is moving to SaaS, the paying for a 4.9 won’t matter for those, as you just pay a monthly fee. In terms of OS, Ubuntu, Debian, a lot use 9 in their versions.

As for apple and macOS 9? Idk who wasn’t please with it. Just like ME and XP, macOS X was not well received by a lot of the more techy people. Hell, there are still people holding onto macOS 9 to this day. The difference from 9 to X was pretty significant in terms of UI, and people don’t usually like change.

Again, I’m curious where you are in the world because I have literally never heard of this. And I’m a developer so I feel like if that was a thing in my neck of the woods I or one of my friends would have heard of it.
