I agree with the OP and all that Vidiot said earlier.
Unlike just about any other religious group - and certainly in contrast with the likes of Scientology - the JW org has nothing to gain from celebrity endorsement and has never really had a comfortable relationship with celebs.
By its very nature, "true" JW lifestyle and theology leaves no room for celebrity culture and status. The very fact they celebrate the leaving behind of high-profile careers and highlight that members should be "no part of the world" heavily mitigates against any sort of celebrity culture in the org. You would certainly never get celebrity endorsements, like famous JWs appearing on the platform at a convention to flash a toothy smile and show off their latest suit/dress! The very idea is ridiculous!
The only JW celebrities where there is no discomfort caused to either them or to the org, are the ones who are low-key and frankly fairly anonymous, like Hank Marvin, George Benson, etc. The loud, proud, flamboyant or high-profile types (like MJ and Prince used to be) have never really benefited the org, nor did they themselves benefit from association with it.
He spoke out against the practice of when a G.B member took to the Platform at a big Convention, the audience would clap them vigorously , before they had spoken a word, dad said that was idolizing them.
Later in life I saw first hand how J.W's sucked up to, and fawned over, prominent Bethel guys, and how those guys, and the G.B are the same, absolutely LOVED the adoration !
Yes, unfortunately, in the absence of a 'real' celebrity culture, the GB turned into the 'celebrities' (along with certain prominent 'helpers'), and that's got much worse since the arrival of the awful JW Broadcasting. The only decent feature of JWB is the ability to show different congregations from around the world, but the high-profile of the GB and their cheesy "we all love you verrry much", coupled with Disney-fied cartoon Bible stories and increasingly desperate use of dramatised scenes is all pretty tiresome.
