The wise thing is to not offer perpetual licenses in the first place. You can’t predict the state of your business in 10 years let alone beyond that. Why make commitments that? Marketing of course. So if they’re going to raise capital that way (by one-time revenue from sales of perpetual licenses) then they can’t just decide that perpetual doesn’t mean perpetual anymore. All in all this will come down to a legal duel between expensive legal teams.
Perpetual licences have their place, like I’m reasonably confident under the hood you have a perpetual licences for the OS your phone runs on. The point isn’t to get a piece of software that will be updated and supported forever, it’s to get something that works, fits your needs, and that you know can’t just be revoked at the whim of another. Problem is that last one is becoming increasingly untrue.
