Is there an open source “drop-in alternative” for really any desktop app of substance? Plenty of excellent alternatives, very few that drop in and don’t have some kind of conceptual differences (even LibreOffice, which after all started as a closed source app).

I don’t think anyone is served well by pursuing blatant cloning in open source. But if this is the shoddy destiny of AI coding then I am at peace with it. People can use lazy knockoffs if they want.
