Dear Vivek, thank you for the note. I am the original author of SymPy. Most people who work on SymPy myself included do it in our free time. So far this has cost many hours of my and many other people's free time to try to figure out what is going on and to get this resolved. I also personally reject your allegations against us. I thought about this situation and how your company could make this right. If you would be willing to help improve the SymPy project, I think it would be very well received. If you are interested, please let us know! See Travis Oliphant's reply, you could for example donate some money to NumFOCUS. We are very good with using money that people or companies donate to fund development and we can really boost SymPy forward big time with a generous donation.
