Ask any mainstream Muslim who the Salafi scholars are in recent times and undoubtedly one of the first names mentioned would be the late Ibn Baz.
Ibn Baz was a harsh critic of Bin Laden and his ideology: https://en.wikipedia.org/wiki/Abd_al-Aziz_ibn_Baz#Osama_bin_...
Here is confirmation from Al Fawzan (the most-respected Saudi scholar now) regarding Ibn Baz's (and his own) position with respect to Bin Laden: https://www.youtube.com/watch?v=1-a65Og2uow
Here is a translated video that includes the speech of a late Yemeni scholar, Muqbil Al Wadi'ee, regarding Bin Laden. It's worth listening to: https://www.youtube.com/watch?v=BO7BcXTc4zw
My point is that anyone can call themselves or ascribe themselves to anything. However, that doesn't necessarily make it a reality (yeah, yeah, no true Scotsman).
