Everywhere I've worked the managers liked Sublimes model too. To the point where at one place we built a few plugins for Sublime because so many of the engineers were using it. It was cheap enough that reimbursing engineers for the license was easy to get approved and everyone liked being able to hold onto their individual license after.
Jetbrains tools are the same; you can buy personal subscription, and use the tools no matter where you work.
If you have a subscription for 12 consecutive months, you get perpetual fallback license for version of the tools that were available at the start of the period.
LINQPad's model is similar but it didn't stop my last company refusing to allow me to use my personal copy due to "licensing". Some companies (read: managers) just can't be f'd reading a brief web page and applying 10 seconds of thought even if it means there's a chance a developer might be more productive, or god forbid, happier.
