I have CDs from software I bought in the 90s I can install today (probably in a VM). I bought it, I should be able to make it work SOMEHOW for the next 100 years. Just release an update with the phone-home commented out.
The issue here is more about remote authorization in the first place. It’s funny to have this conversation after the fact. It probably should have come before Finale shut down. People against the idea of disabling new authorizations should, instead of complaining about Finale, proactively work to make remote software authorization illegal in the first place. Remote authorization always comes with the risk that authorization will be disabled. I’m guessing it was supposed to be a copy protection scheme, which is widespread and common, not a way to shutdown use. But here we are.
They chose not to release an update with phone home commented out. It was, therefore, a business decision, not a technical one. I understand the reactions to this decision, but I have serious doubts about the claims of harm or number of users who will want to run Finale in 12 months.
How much of the software you have from the 90s do you actually use? Be honest. I hardly ever use any of the software I have. I was a packrat and collected things I thought I was going to use, but 30 years later, I don’t use it.
