Reading further through this mess of a suggestion, there's one paragraph I must address. I decided to use a separate answer for this, as the point is completely unrelated to whether or not we should DV / close questions.
A recent case made it clear: the internal stance of Stack Overflow is diametrically opposed to what programmers expect from it. A volunteer, Jan Schultke, who made a habit of "regularly modernizing C++ questions and answers by adding notes or changes based on more recent versions", had been reproached for it. And decided to ask a question on Meta, When do modernization edits conflict with the author's intent?, which, to me, boils down to a more generic "Whether old but popular answers should be updated or left as is?". And active users of Stack Overflow voted for the latter: on the next day the question had -10 and a sole answer suggesting to leave old answers alone had about +20. But after I posted the link on Reddit, the question changed its score to positive and got quite a reasonable answer supporting the modernization of old answers, while the comments on Reddit agreed on "that's what I would hope to see on SO".
That OP is new to Meta. He's made multiple suggestions on here that are completely out of touch with the community consensus. He's also been rather argumentative with any and everyone that disagreed with him...
Being the author of the (currently highest scoring) answer you mentioned there, I was very surprised that the suggestion was inexplicably, out of nowhere, getting a lot of upvotes.
Now it makes sense. You dragged it into social media.
I should probably disclose that I wrote one of the answers there. Just wanted a look from the programming community outside the close clique of SO functionaries. (source)
You know, Reddit, not exactly the most neurtalneutral of social networks. There are a lot of discussions there that indicate the participants' frustrations are based on a misunderstanding of how SO works.
Of course they're gonna disagree with any and all curative efforts. They've got no stake in SO.
Frankly, I think it's very low that you'd use external social media to boost your own answer, artificially inflating the votes on it.
To me, that alone completely invalidates the point you're trying to make...
And after this answer was posted, this discussion was reposted to Reddit, by the OP...
Brigading like that is very much in conflict with internet etiquette.
It has resulted in harassment and skewed vote counts.
(Sure, we can't "know" the source of votes, but it's a pretty safe guess)
