I didn't notice the change, since I am a paying user for a couple of years.
But this sucks.
I'm an asshole. I've always used it for "commercial reasons", since I used it for work. But I found it so useful that I felt bad and bought the Pro license.
In your particular case, since you're not using it as much, maybe a different GUI would be enough (https://git-scm.com/downloads/guis). I don't like any of them personally, but I would tolerate some of them if I didn't have to use it every day.
Please don't do this. If you're a student, you can get it for free from the Github Student Developer Pack. If you work for a charitable cause, you can apply for a license through our Pro For A Cause program.
