Same here. I used to answer a lot of android stuff when android was new and eventually it got too big and a lot of lazy questions got pretty much spammed. I loved helping people (I think out of ~400 posts two were my own questions) but eventually you get tired of "my toast isnt showing" or any other question like that. I gave people the benefit of the doubt as much as possible, but in some instances I could copy the question title, paste it as-is into google and the first hit was the answer.
Eventually I just deleted my account and left since my motivation to answer stuff over there was a bit more than "I'd like to help people". I also liked to find questions I can't answer and figure out how to solve them on my own. Those became buried under lazy questions to a point where I had to dig for hours to find one. Maybe android was/is a bit of an extreme case, but still I see the same pattern more or less when I occasionally browse SO after finding an answer to my own problems over there.
As for the OP, I think a lot of people don't get the SO format. Yes, that post contains a lot of very useful information. That's great, but: No it's still not a good fit for SO, SO is for specific questions with a clear answer and that post isn't that. It's overly broad in scope and has no right answer. One can argue about whether deleting really helps anybody (don't think so personally), but closing it seems appropriate considering how the site is supposed to work.
