And hiring Anders Hejlsberg
Bad management, bad decisions, bad products (Delphi 7 was peak). MS had nothing to do with that. And I'm sure Anders made a right move to abandon the sinking ship.
I'm still pissed at Borland for all those bad moves.
Just to be clear: we are talking the 90s here. Everybody was charging for developer tools (). MSDN was not free, far from it. From today's viewpoint where every compiler imaginable is free and the tools are better than ever (except there is nothing like Delphi and VCL), the 90s were a heaven for tool makers.
I'm talking about the Windows ecosystem.
Not free but low enough so that invidual developers and companies wouldn't think twice about bying a license.
Borland/Inprise/Codegear/Embarcadero just priced themselves out of the market.
