I could of course go to a startup or something, but I have a wife in school and a mortgage to pay. I don't really mind upheaving my life to take a bit of a risk on a startup, but I think it might be a bit selfish if there's a risk of it causing problems for other people.
Alternatively you could try to convince your employer to add an exception to the non-compete. It's not unthinkable that they would allow it, if it's just for blogging.
That said, you're not wrong; I probably could harass someone to be allowed to blog, but after being declined twice from contributing to open source (both taking around 4-5 hours of talking to legal teams and managers), I'm just a bit burnt out from the experiences.
I should probably find another job once a bit more stock vests.
