The existence of the blog itself makes me think the truth wouldn't be as clear as it is presented. Was every rejected talk proposal accompanied by emails and tweets asking for explanation? One can be polite and annoying at the same time.

(that being said, their email reply was still unprofessional)

Yes, I asked for explanation of rejected proposals in 2017 and 2018. And I received it (they even officially encouraged failed proposers to ask for an explanation).
