> Microsoft and Apple have massive vested interests in supporting their languages and platforms. They stand to lose a lot to their core businesses if they stop. Developers’ interests align somewhat with theirs in this regard: one developer doesn’t have a lot of power in those relationships, but the sum of all developers definitely does, so these companies generally need to care for these languages and maintain these platforms for a long time.
This reasoning fails dismally when applied to Microsoft's own technologies: VB6, Silverlight, Windows 8 Phone (original version). All these developers cast out. There are surely more examples.
