I think it's simple:
In the Shepard The Flock book there are official reasons that
one can be disfellowshiped for:

- Employment violating Christian principles - km 9/76 p.6, km 2/74
- Working for any religious organization - ks91-E p.95
- Working in a gambling institution - ks91-E p.136
- Selling tobacco - ks91-E p.96
- Contract work at a military establishment
While contract work at a military establishment is Banned for a JW apparently the WTBTS receiving the profits is not.

Founded in the 70s, the trust´s sole purpose is to generate equity returns that, after deduction of treasury costs, flow 100% to the WTBTS. The trust is being managed and supervised by employees of the Comerica Bank in Detroit.
The trust is quasi "owned by itself". The capital is being lent to companies to work with, and they return a part of their earnings to the pot, and these gains are given to and accepted by the WTBTS.
This particular Trust is invested in companies that make products/ weapons for the military.
R rated movies and soft porn is associated with other companies that are in the Trusts holdings.
