It's not just the 'tight pants'... This thing is rife with subliminal messages
Notice the hair styles. One guy has a 'high and tight' kinda cut, the other has the 'messy, just got out of bed look'. Both are fashionable, I see them in the service industry, the business world, and just out and about. Nothing immodest, just different than what older folks (or conservative cult leaders) are used to.
Another subliminal message: notice the hip young dudes have their smartphones in hand, while our modest, god fearing, WTS ass kissing examples of cult zombieness do not. The message? The obedient ones are discussing the upcoming WT study, not checking the scores from the NFL game (or checking out Snapchat).
The WTS leadership can't allow freedom of expression. They must maintain control. Anything that doesn't fit the conservative mold of obedience must be condemned.
