I took a look at gpui-component a while ago when assessing GPUI for a project I was working on. IANAL but was dissuaded because it's almost certainly not compliant with the Zed license--gpui-component "borrows" gpui code patterns lifted straight from the main zed repo, which therefore must be AGPL/GPL (unlike the gpui-only which is Apache IIRC). Caveat emptor (caveat user?).
