IntelliJ Ultimate is $500 for a commercial license I believe (and you need a commercial license to do work for a company over a certain size, even if you pay for it yourself). Sure it's not going to affect my finances either way but:

1. The 2 minutes it takes to file an expense report is a good trade for $200 (I don't make $6,000 an hour at my job)

2. It's the principle; they should pay for it, not me.

No, you don't have to do that¹. Where did you get that info? I don't want to argue your personal value calculation and I accept that you feel the way you do, so let's set that part aside.

I've been using my IntelliJ licence at multiple jobs on my own and AFAIK if I don't get it reimbursed I don't need a business licence.

Ah you're right, I stand corrected on the license.

I don't see the value calculation as an emotional one, I truly don't see a reason not to fill out the expense report

I didn't mean to imply that it was emotional, just that it is your own preference and different from mine. Personal there as relating to your person.

Sorry, needed to clarify that, but I really don't want to argue this point with you.
