Other televangelists don`t seem to have any trouble raking in the money so i don`t see why it would be a problem for the WT religion. Selling off all of the KH`s and making wise investments could be a way to go.

They could also claim they have the potential to reach many more millions of people that they otherwise can`t reach in today`s world .
