well, as a long time developer in financial enterprise space (18 years) I think MS made a lot of right moves already since Nadela took over. betting all your eggs on Windows dominance proved to be a faulty (and dangerous) strategy especially since a lot of enterprise started using Linux / open source. For example I know a very major hedge fund that went from Windows everywhere to using every open source database they can get their hands on. The whole container strategy is just much easier with linux as well. it's a very hard battle to win. one big co vs every startup betting on OS.
