You're missing his first major offense: Going on live TV at the mayor's press conference in front of a tremendous audience to masser on a shul near him. He wasn't ashamed to give full details, address and all on live TV and complain to the mayor why he's not enforcing... And that there's many more that are open too that he doesn't have full details yet.
That was just low.
This was in March when people were dropping like flies. He felt, and there were many rabonim that agreed, it was sakanos nefashos. In hindsight, he was wrong. But to call him a Nazi, Kapo (how can you be both?), moser, etc. based on pikuach nefesh, come on.
This is now 6 months later. The media was in Borough Park before the protests. Yes, he exagerrated things, and yes, I'm no fan of his, but people are overblowing his affect. As I said earlier, ESH, but in the search to find one boogeyman to blame everything on, people are finding JK or HT. The truth is, there is no one single issue at play.
