I had a similar thing happen. The CTO of a company was using a library I wrote, and he ran into things he wanted to change. When I disagreed, I was accused of sabotaging my own library, by refusing to fix it's obviously broken aspects. Guy went on a smear campaign on hn, Reddit, Twitter, Wikipedia. Literally made me miserable for weeks.

I wrote about it, more here if you're curious:
