If people are displaying good intentions, and not wildly ignoring a load of clear instructions, then engaging with them will have a much greater chance of producing an educated, productive member of the community, and the more of those the better.
Microsoft surely has the means to hire someone who is not an eight year old using their computer for the first time.
This error is actually a good thing from point of view - it's an anecdatum that the whole* company is engaging with open source, not just the bits that know it well. This is something we should encourage and educate. The advantage of educating someone at Microsoft as that their institutional knowledge will persist some fraction of it, so that the next person that comes along is less likely to have issues.
That said, I'm pretty sure the original author knew and understood exactly what they were doing - writing a dirty hack.
On your development machine or on machines of other people all around the world? You can also gain understanding from the later, too.
The great thing about those early machines ( Apple ][+ ) is that the dynamic programming language was the OS and was the REPL and that was all in ROM, so you could tinker around to your heart's content and hit the Reset button if you got stuck. That's a context that's just fine for learning. Packaging for archives installed on other's machines aren't that kind of context.
A kid gets to play in a playroom with some toys, not in a surgical theater or a machine shop.
I'm still willing to write worse! As a temporary hack with a JIRA issue tracking it, to unblock work, and with the intention of fixing it quickly, but still willing nonetheless.
Meanwhile the code blocks on this website lose their scrollbar and pop atop everything if you hover over them, making it near impossible to scroll right through some kind of abuse of JavaScript. Why?!? Shall I snark about incompetence too? I can't even rationalize this one to myself as a means of unblocking development like I can with the packaging hack!
I think I would have done a little bit of reading. I also think it's the norm.
