Still sounds gross. While the developer might have opted in to selling your processing power to scrape websites, I doubt the users of each extension opted in.

The popular Dark Reader is not affected by this as far as I know. Only this knock off for the edge browser. Source: https://docs.google.com/spreadsheets/d/e/2PACX-1vT1XgBs25gRlg5e3nYCAff967WMtZZTO-TB3rR9zszaJpTpCVFg8j7FkBxnHb3tw3aHGjKBGSxYyLgV/pubhtml

I use the inbuild Dark Mode in Vivaldi (on/off with shortcut, wors even in intern pages and menus) and none of the extensions from the list, most extensions from the Store anyway are redundant in Vivaldi translation, reader mode, tabs, feeds, ad/tracker blocker..........)
