From what I can tell, Microsoft isn't even sabotaging open alternatives, they're just Not As Good. That sucks, but that's just how it works when you're using software made by a company that likes to pay its staff and still make a profit.
I welcome everyone who feels entitled to the source code of Microsoft's very best software to see what true open source, maintained by an independent non-profit organisation looks like. You'll get an IDE that's functional, maybe even features a real debugger, but you'll probably wish you could go back not long after.
People are taking software given to them free of charge for granted. It's not that long ago that you had to buy IDEs for hundreds or thousands of dollars and you had to buy the upgrade if you wanted the next version a couple of years later.
