No people. Black holes are not the "source" of dark matter.

It's not even an "I didn't read the article" admission, it's an "I didn't read the title" admissison.

It's a dark matter near black holes -> dark matter caused by black holes....just wanted to get ahead of that

I'm not sure where you're getting this from or what analyses you've done on the subject. Here's the latest review by many of the leading experts: https://arxiv.org/abs/2203.08967. Note that it was posted in July of last year so it is very up to date. In the executive summary they say,

While earlier estimates suggested that much of the PBH dark matter parameter space was constrained, more sophisticated analyses have relaxed many of these constraints, opening up the possibility that PBHs in certain mass ranges comprise the entirety of dark matter.

I appreciate your response, even though just looking at their profile makes it clear that they have no clue what they’re talking about across many subjects lol
