Agreed. I think more/most commercial software will use the subscription model.
My idea about the reason for this is: a) it's greed of the manufactorers, but also b) we have reached a saturation in benefits from (buying) newer versions of software.
Nobody really needs Windows 11 and the latest MS Office version for doing regular office work. There's just not that one shiny new set of features that makes you switch to Windows 11. So MS must force people to use it.
Same holds for Adobe Suite and creative work, with only a few exceptions (like supporting new camera RAW formats and stuff).
So, manufacturers want to force users into the subscription plan.
Open Source doesn't need to do so.
