How uneducated do you have to be on the topic to believe this? Me? I'm betting some corporate lawyer said they could probably get away with it.
I don't think that running a hotel requires any knowledge about spectrum licensing. The move to block was probably motivated on two fronts:
- Potential for additional profit
- Support requests from guests having problems with their personal hotspots
Also, when it comes down to it, once they'd made the initial plans to roll out blocking, the best possible path forward (legally, at least) would be to operate as if you fully thought it was legal, and to not document any dissent.
"Innocent mistake" is a much more defensible position than "informed infringement."
