This is complete stupidity for a busy commercial operation. Let us face it, normal tower ops could be / is almost procedural. Flying is often done in very low vis. However, apart from the real benefit of local knowledge, being on-site and working locally, primarily visually, gives so much better direct information to the controller that, it should not be sacrificed.
There is no problem with providing the controller with synthetic displays for low vis ops but, putting the total control out to some lowest bidder in their bedroom, totally vulnerable to the vagaries of IT is pure stupidity IMO.
