That fully Microsoft and windows stack has had ripple effects. At least from my perspective in South Asia. First the price was a deal breaker. Second, people who started with C# quickly found their only employment opportunities to be at large companies. Those who started with Java/Node/Ruby had a much wider array to choose from. Third, when people jumped to start their own companies, Java/Node/Ruby/Python/Go won by a large margin. Startups rarely had the cash to spare for Microsoft stack and MS stack guys had to change their skill sets which is a painful endeavour in and of itself. Fourth, after some time people, who had been in the market for years, started discouraging younger devs to committing exclusively to a full MS stack. People rather interpreted it as dumping the MS stack. In my batch, only a dozen or so people were interested in pursuing C#/.Net. By the time we graduated only one person was still pursuing that stack.

TLDR; Price was a big factor which only large companies could afford. Not everyone can be employed by large companies. This had a lot of secondary effects.
