Possible solutions to affect some justice and reclaim your image:

  1. Fire WorthIT Solutions (no RCA necessary, do not automate or outsource DMCA, even if it's human based automation)
  2. Apologise to SymPy
  3. Discuss internally the cost-vs-benefit (more than monetary) of embarking on copyright policing as part of your company's future strategy
  4. Blog results of #3

WRT #3, sustainability comes to mind - if dissemination of solutions is a serious threat to your current business model/implementation (something you might want to validate anyway) then consider adapting to mitigate it to the point of irrelevance. Perhaps you are already doing this, but DMCA policing is at best a distraction and at worst a PR nightmare and menace to FOSS like today, it also doesn't scale well.
