I got loads of time for that, but I've also suffered at the hands of MSBuild as have thousands of others so the PR seemed like a funny troll at the time.
Seriously - I remember at one client there was a specific machine set up to edit the build on because it was the only one that could open the workflow editor without crashing. Why there was a workflow editor to edit MSBuild stuff I don't know but that's that world in a nutshell.
I don't disagree that people have problems with Microsoft products but I would just suggest asking yourself whether the people who went to the trouble of open-sourcing something are likely to want those problems to exist rather than, say, engineers trying to do what they can at a big, complicated company. Is it more likely that the person who reads a troll PR is going to say “I had no idea everyone wasn't happy with this!” or that their boss will say “See, I told you that releasing this was a waste of time”.
IMO the PR is not only disrespectful but also utterly wrong, from a technical point of view.
If Make was that awesome of a project, it would have evolved to cover the needs of most developers, however, some tools grew around it to "workaround" its limitations, and then the monster called autotools was born.
I consider MSBuild much less worse than autotools. I'm not yet a fan of any build tool to recognise that it's good, but at least I can tell that MSBuild is one that sucks the least.
PR are not the place for jokes. Developers have enough to do managing their projects, they don't need to waste time sorting through jokes.
You might say, "it's just one joke, what's the big deal?" One joke, attracts others. Everyone thinks they're funny and their joke with worth everyone else's time to read it. If PR become a place that's acceptable to make jokes, it'll be flooded with noise.
There's a well-established tradition of pull requests and issues being used for commentary and humor.
Here's a selection. The first one is by the founder CEO of a company with a ~$1B valuation that's prepping for an IPO and is very similar to the one everyone here is complaining about. The second one has comments from a couple well-known tech folks. And so on...
The girl represents MS being proud of itself for open sourcing something the two blokes consider irrelevant, as they head to the pub for a nice pint of Make.
That's my interpretation (and not my sentiment - I'd rather MS open-source tools like this than not).
You absolutely were being an annoying prick. The best thing you can do is own up to it and apologize. Definitely not what you're doing right now, what with the whole "jees, what is your issue" thing.
The reason he's so touchy about it is he's a narcissistic annoying prick. He only did it for attention since people pay attention to bullies, and it requires no work or intelligence unlike being paid attention to for contributing constructively. Call him out as an obnoxious bully and his ego can't stand it.
