Earlier quoted context omitted.
Before Microsoft bought them they were basically at a standstill and no new features were being added to the product. At least, that's my recollection of it, perhaps someone can correct me if I'm wrong.
My screwdriver doesn’t seem to need more features. It’s nice stable and reliable.
EDIT: Sorry, this is incorrect. GH did ship them prior to the MS acquisition. I do however remember them taking an EXTREMELY long time to ship emoji reactions, which struck me as a fairly trivial feature. I stand by the point that GH ships features faster post-acquisition, though.
