I disliked the IntelliJ move because I have a preference for owning over renting. Possibly because I grew up in a country with a preference for owning property and seeing rent as dead money, or because I grew up buying and collecting CDs and putting them into alphabetical order.

In this case, I am happy to pay for RubyMine. And happy to pay a little more if I want to update to the latest version. But I don't like the idea of only being able to use it this month as long as I've paid the rent.
