That's certainly one perspective....But, another could be that you could now be considered an expert in your library, and your old company's direct competitors are free to hire you for this expertise. This of course needs to take into considerations whatever agreements you have/had with your old company. Yet another perspective is that your old compoany could hire you as a highly-paid consultant to help them support your library, etc...In this latter case, you "win" because you're not helping competitors, and your old company "hurts" ever so slightly by needing to pay you hopefully more than when they had employed you....i'm sure there are other opportunities for you - that have and have not to do with your old employer/company. Then, there's also the more philosopihical perspective: don't look back, just forget them, and move on with your life. :-)

Except that the company might be interested in paying you to use the library, not to maintain the library itself.

"don't look back, just forget them, and move on with your life" is a better advice.
