Borland was going broke because they abandoned their core target market for chasing after the enterprise - and that was during a time before open source even got its name and developers expecting tools for free was a thing. And have you seen the reputation these systems you mention have among developers (assuming they know about them, after all my original point was that the "enterprise pockets" requirements lead to obscurity - with the obvious exception of those that have been around for a very long time) and how clunky they are? Turbo Pascal and early Delphi never had the reputation that Oracle has nowadays. And sure, you can find works with them but these systems are a minority and when they are used they are practically never chosen by developers themselves.
