I don't think Jetbrains would be where they are today if not for personal license that grants the right no use the software on as many machines as I like. When it was introduced it cost just slightly more than 3 technical books, and I knew a couple of people who used that math to convince others to switch to Jetbrains.

That license is worded specifically for me to use my private copy at work without exposing my employer to liability.

It's surprising to me that more organizations haven't followed suit. But many of these tools run either on the server or on a CI/CD machine so I'm not sure how you'd work that.
