No, it is not true. I'm not sure how you came to that assumption, but the Spine Essential and Professional licenses cover all future updates. 🙂
We've considered doing paid updates, eg you'd get updates for 1 year then need to pay again to get more updates. On one hand we continue to work on Spine, so it would be nice to have some recurring incoming to cover that. On the other hand, there are a number of complexities doing that: the editor export needs to match a specific Git version of the Spine Runtimes, the launcher needs to be even more sophisticated (it's surprisingly complex already, even though it appears at first to have a simple job!), if people don't have the latest they would suffer from old bugs until they paid to upgrade, same goes for new runtimes features, etc.
In the end we decided paid updates are a pain for us and pain for you guys. Instead we have the Enterprise license, which lasts 1 year then needs to be renewed. The idea is that only larger companies provide us with recurring income, since they have the resources for that and are positioned to get more use out of Spine. It's a sort of robin hood approach that punishes the rich and gives the poor a break. 😉 This is also why we charge a relatively high initial cost for Spine, because we won't be milking our users for updates over time (unless you end up qualifying for Enterprise, in which case congratulations!).
