Now I'm glad I've not opened VSCodium in a few weeks; I prefer using Claude as a separate application anyways, will have to remove the extensions.
No evidence, but I do feel like the problem is going to be OpenVSX and not Anthropic.

Edit: Ah, guess it was not open-vsx, but a in-house Cursor marketplace. https://news.ycombinator.com/item?id=50304129
