That's a pretty good display of the nonsense of SaaS.
Someone who has paid for premium will find itself with a shitty export that won't be usable without investing a lot of time into importing somewhere else or making some sort of software to exploit it.
And there is no way to prolong its useful life by keeping an old system around or make it work in a VM. Subscription software is a travesty and only cares about extracting the most money from customers. It's not even worth much in terms of compute requirements because you still need to invest in decent hardware for other softwares (that most likely won't ever be able to be fully remote).
Web software isn't bad but the hostage situation it allows is pretty bad. But then again, even Apple with their pride in native local software has pushed subscription to extract the most money possible, so... Greed is such a destructive sin.
