A perpetual license doesn’t mean the company supports it forever; you know that, right? I have a copy of Quickbooks 2015 that I got the license key for from a closing company for about $25. I will never have to pay another dime for it, it’s a perpetual license and will run indefinitely. I just don’t get any updates at all, and I can’t run anything that requires updates or subscriptions like payroll or advanced features. But that’s absolutely fine for my purposes and works the same for many, many people. This is how things should be - if I’m fine with using an outdated version, there is zero reason I need a subscription license.
Look, I’m sure his surgeon did the best they could, but even masters can struggle when they’re working with a subpar medium.
