This is a highly suboptimal solution to a problem that doesn't have to exist. If the application as it exists meets my needs, but an update makes it worse, I should be able to keep using the good one.

If I just buy the application rather than license it, it won't change unless I choose for it to by buying the next version. That is ideal.

There are a number of reasons why I avoid software subscriptions, but this is one of the biggest ones.
