I talked to tech support and they confirmed that they don't care about customers.
"You can not access 2020 software and earlier and there is nothing we can about it."
At minimum I would expect the company to at least allow you to open your old save files and export them to the raw forms so you could take the data somewhere else.
I have never encountered a company that simply refuses to allow customers to access their own data.
This would be a violation of data transport in GDPR in Europe from my understanding.
This feels a lot like a class action lawsuit to me...
