Exactly this. The financial investment is not the issue here, it's the investment of time and mental energy into integrating the tool into my workflow and becoming dependent on it. I do not expect them to develop new features indefinitely for free, but I would like it to continue to be supported and developed, even if that means a new paid release every year or so. I'd gladly continue paying for new major releases.
As it is, we'll probably get a compatibility release for anything that may break with the next OS update and not much beyond that. Come several years from now and it may simply not work anymore because of an OS change. That's my primary concern. Being abandonware with an unspecified, vague promise of critical fixes makes it seem questionable whether there's any value in continuing to use it vs. investing time in switching to another tool (of which there are few to none which work perfectly for my particular workflow) up front before it does inevitably stop working down the road.
