Who has STRONGEST claim to being the REAL heavyweight champion?

All questions will be removed after the fight between the winners pairs Joshua-Pulev and Wilder-Ortiz

 

I wonder why Ring is still boasting Fury as their Heavyweight champion. How many of their rules does he have to break in order to finally get stripped?
Exactly 2 months from now he's actually at a point where he has broken anywhere between 3 and 5 of their 6 championship rules, depending on interpetation and rulings.

So, what's keeping them from stripping him as he had already 2 championship rules violations at least, with 2 others in the grey area at this point.
It's not like he's going to have any change having succes suing them at this point, so what gives?

That said, I think that anyone without any bias would point towards Joshua as the current #1 at HW.

 

There can be no claim as to who the real heavyweight champion is as they are all real champions. You can argue who is the best but that can only truly be decided in a face off involving the three current champions.
