old article from 2010 about ms spreading fud http://blog.wolfire.com/2010/01/Why-you-should-use-OpenGL-and-not-DirectX
I still remember this specific article and it struck a nerve with me when I first read it.
I'm sure there are much older examples and also much newer examples but this one is always in the back of my head.
latest example I can think of off the top of my head is ms adding their bash compatible terminal or linux subsystem, not sure how it technically works, but it allows running bash scripts and I think linux terminal commands and tools to some extent. which sounds great on the surface for anyone who wants to do this and might bring some value to the eco system, but it makes me scared because I only see ms infiltrating foss and trying to make it their own and reducing the need to use linux at all, and I suspect eventually they will introduce new things that only works on windows and fragment things. even more scary I commented about this on reddit and only got downvotes. I guess I'll keep all my tinfoil hats for myself and not share with the rest of the class.
another example is xbox trying to buy up every game company and put playstation out of business, with their latest comment being about how they would want to buy up nintendo. I guess technically not ms, but pretty same to me.
I didn't have much interest but there was enough hype that I tried it but found it too slow being used to sublime text. I know lots of others like it a lot though.
last I heard though is they are removing the macos version. which would mean that anyone who likes it enough would need to switch from mac, which sounds too convenient for me to be an accident. I don't know how many would actually make this switch, but it leaves a bad taste in my mouth, and I'm sure there are scenario where development teams are very used to vscode and the ecosystem and perhaps ingrained enough into their workflow that it makes more sense to them to have the team switch to windows to keep using vscode instead of rewriting solutions and/or having the developers spend time to relearn and get up to speed with another editor and plugins etc.
