I've been a subscriber for the last few years. MM is worth the price to me but mostly because I'm very lazy. I can understand why people don't want to pay for it. You can find free alternatives for almost every feature but you may end up cobbling together half a dozen or more apps/services. This requires more time and effort to setup and maintain than I'm willing to invest for something so mundane. If Apple goes free they just need to be prepared for an influx of millions of users overnight.
