I think you've hit on that once a company goes under, basically you're stuck with whatever lock-in at the time. Sure a SaaS could evaporate tomorrow, but even desktop apps get old and start breaking within a year or two, faster if it's using some tech that Apple is trying to get rid of. At this point, it's funny because the business has the leverage, even though it's going under. I guess you can sell the code / rights, or open source... To be fair, this problem is everywhere. Open source projects are abandoned all the time.
