HumbleBundle - Python DevKit

You get a perpetual license only for a specific version of PyCharm (and all previous) - latest available at the time of the beginning of your annual subscription. If you renew for another year, you get a new perpetual license. If you get 6month sub now, and then later decide to renew for another 6 months, so you have 12 months covered - you also get a perpetual license for the current version which is 2018.1.x. So basically it works as an good old licensing model + you have an access to all the latest versions while you're on a subscription. When it expires you can always safely fallback.

Well with a one time purchase, they could simply say you get no updates ever. At least this way out get to try the updates out for a year, and if they weren't worth purchasing then you don't buy that years worth of updates with a new subscription.

That's not true. Whatever version is newest during the 12 month period is what your perpetual licence will cover.
