Yes, same here. Forgot about the fact I forked the iamadamdev/bypass-paywalls-chrome at some point. Reading the notice, it looks like they are going after all forks and derivatives of this addon, including the "clean fork" here: https://github.com/bpc-clone. Also looks like they got rid of the filters list here: https://github.com/bpc-clone/bypass-paywalls-clean-filters

Update: looks like the clean fork is hosted here. https://gitflic.ru/project/magnolia1234/ (It's hosted in Russia, so YMMV).
