Is there a ticket code or other contact you've been in touch with?
As for DMCA filings, we publish all of them here: https://github.com/github/dmca
I see two from Photopea, one from 2022 (https://github.com/github/dmca/blob/d97814f268e07e62aabe8b5c...) and one from 2024 (https://github.com/github/dmca/blob/d97814f268e07e62aabe8b5c...) - could you point to the recent filing?
I work at GH, but am not involved in DMCA filings, and can in no way answer or judge this case, but potentially follow up internally.
Thanks! One is Ticket 4822535, another is Ticket 4726557.
Github did take down this https://github.com/spooknik/Photopea-Appimage and other repos in the past, but now, I feel like I talk to a robot. I am happy to hear that they have real employee! :D
