On one hand, this is a tempest in a teapot. Big deal. Apple Watch. Some wealthy dub probably gave it to him. Not really a scandal or worth worrying about.
On the other hand, as pointed out already, the leadership is constantly harassing the R&F to avoid materialism, and to work menial jobs, and spurn higher education. So it is fairly hypocritical, and a slap in the face to all those that follow their 'advice'...if they were actually paying attention.
I say, let em wear all the bling they want. Wear expensive suits, shoes, accessories, watches, rings. Go ahead and look like the con man TV preacher you really are. Maybe some dubs will start to see there's no real difference from the men they worship and the men that other dupes worship.
