No. I'm very clear with demands on my time that either companies have to provide resources to implement features (and I'll charge a consulting fee to train devs) or pay me directly to implement them (and I'll name the cost). Actually, several companies have paid me, and my project is significantly smaller than homebrew (niche Haskell library).

I don't really care about being vilified online. Have had my fair share. I'm old enough to not give a second thought to online trolls.

Or... don't change the license. Stop giving updates, and put up a notice that says you are not actively working on project X but for a fee you will be happy to make updates.

I wish them every success, and I may end up using it myself. However, I don't like the accusations of unfairness being levied against open source users (among which I would also include myself) for using freely available code for free.
