As someone who follows both it actually started with PJ and for a long while Florian never responded. And even the responses were far more professional than PJ's usually hyperbolic posts.
And being paid by a company does not make you a shill. Bias comes in many, many forms and the only way to cut through it is to provide facts.

The fact that Florian likes to brag about his dubious credentials while PJ lets her analysis stand on its own merit really adds to it. Florian believes his identity to be vital to the worth of what he says, PJ thinks the opposite of herself.
Go read some of Florian's rants about PJ, and tell me with a straight face that you don't find it creepy and are surprised that she would choose to keep identity out of it.
I'm well aware that I'm as guilty of it as anyone.
