For the lack of a better example, think of it in mobile phone terms... you may have a formerly offered unlimited plan for $99/mo. A great deal and it may very well suit your needs perfectly, in which case, you'd naturally keep it indefinitely. It's unreasonable, however, to expect all of the enhancements, subsidized phone prices and other benefits, without renewing your contract and selecting a currently-offered package, so-to-speak. If you want to keep your $99/unlimited plan; fantastic - your service will be the same as it always has! Unfortunately, you can't have the benefit of the old, promotional plan AND the advantage of getting all of the enhancements, access to the newest phones, etc. It just doesn't work that way.
Sorry if you feel you're being forced out of your license -- that's certainly not the case. If you're like Nimdock and aren't interested in the enhancements and the license itself is more important to you, by all means, continue on - we encourage you to do so if it meets your needs. Unfortunately, we can't offer it both ways, folks.
