JetBrains subscription model isn't too bad. If you buy month-to-month it is like any other sub model (access dies at the end of the month/subscription period) but if you buy annually you get a perpetual license for that version so it is kind of like just buying a version outright.
Of course the subscription model gives JetBrains more incentive to keep revving the version number so if you want to stay up to date with the latest and great you have to keep "buying" it every year but C'est la vie.
The rise of this phenomenon is doing more than almost any other event to drive me to FOSS options.
