Very few people object to paying for updates as an option. The expectation is that if you got a version now and it works fine, then you should be able to keep using it without paying. It's only fair, because after all developer costs here are exactly zero. If later on you see an update with something you like, then you pay again. That's the model a lot of Windows desktop software is rapidly converging to and it's a good fit for subscriptions, as a convenience option. In comparison, any software that drops completely dead once you stop paying comes across as a rip-off and quite rightfully so.
