In other words, no matter how silly and innocent the passing reference to IMAX is, is it possible that IMAX lawyers must pursue those genericized uses even though those lawyers (and the client IMAX itself) knows it generates negative publicity?
A natural human tendency is to speak with similes & metaphors. "Yosemite Valley is like a jacked up IMAX for nature lovers" or "my budding friend the film student with his overuse of lens flares thinks he's the second coming of J.J. Abrahams".
The tension between trademark enforcements and natural human tendencies to color conversations with innocuous references to pop culture creates silly-looking "cease & desist" letters.
