I quit my day job immediately

I think that is smart for other reasons in addition to those you mentioned. I've seen plenty of articles posted to HN where people were sued by their former employer claiming that their corporate time and resources such as intellectual property were used in the production of the product. It often turns out to be false accusations but the wasted time and money from the legal battle is not worth it. Leaving the employer first may preclude such shenanigans.
