Outside of MO circles “Rabbi Soloveitchik” is more likely to mean any one of the Brisker Rovs, past or present. They are, after all, the original and famous Soloveitchiks (and the family that RJBS decends from.) Which leads to the point, in many if not most online discussions MO commenters refer to him with the brief “RJBS”. They do the same for other rabbis to (i.e. RMW for Rabbi Willig, RHS for Rabbi Schachter, etc.) So it is obvious no ill will is intended with these abbreviations and it is the accepted and common form of abbreviating.
