I suspect age difference has an effect, here.
Since Netscape was taken down, we've seen a world where hackers can execute an idea and become successful based on their execution, sometimes abundantly so. I do not think it's accidental that this period largely coincides with Microsoft losing their anti-trust case.
Before then, Microsoft would just wait until a market formed, then take it over or destroy it by bundling something with one of their monopoly products. People who had a dream of creating a successful software business knew Microsoft's business practices made that extremely unlikely.
So, yes, many developers who were around during Microsoft's heyday likely are carrying a grudge that must seem juvenile to anyone familiar with the much less threatening Microsoft of today. Whether it's juvenile to have bad feelings towards an organization that snuffed out a lot of optimism and ambition, I'll leave to you to decide.
