The corporate-owned, single-vendor product angle is a debatable point.
Couldn't you say that about --- hmm, lessee --- C being started at Bell
Labs, Smalltalk being started at Xerox PARC, Java being started at Sun,
etc.? Plenty of languages were started by companies and weren't
collaborative FOSS. That doesn't mean they are inherently flawed or
unworthy of consideration because of that. Now Microsoft being behind
languages such as C# and whatnot could restrict platform implementation
to Windows only. But then again look at Mono. Plus with Microsoft's
WPF/E the intent is to deploy .NET to a variety of devices, not just
Windows PC's. There will be a WPF/E plug-in for web browsers such as
Safari, Mozilla, Opera, etc.
