[AccessD] Secured vs. Unsecured FEs

How many independent contractors in the group 
provide the Access FE to their customers 
either as an MDE, or, as a secured MDB, so 
  (a) changes can't be made, and, 
  (b) the VBA is password protected?

I have my reasons for doing so,
(fixing some amateur's efforts to
 add an enhancement; protecting
 my not small investment in 
 training and upskilling; these two
 will do to start)
 
and of course there are arguments against.  

Can I have some input please.  Both sides
of the argument are welcome.

TIA
