You don't "own" your instance of Basecamp, you just rent it. And there's nothing wrong with that. Some might disagree. Personally I find SaaS to be a general business imposition with significant long-term costs in terms of lock-in, operational expenditure, and an inherently poor negotiating position with the vendor. I dislike required service contracts or yearly per-head licensing fees for the same reason. With more openly licensed software, a key differentiator is that we can choose to continue to use a previous version of the software, whereas if we cease paying for a service, we must migrate all operations, data, and training.
