Earlier quoted context omitted.
The post also mentions that hot tub interviews at Facebook New York are completely untrue. Then goes on to say what is true, which is that there's a non-functioning hot tub in Facebook Seattle which is never used for interviews. To be completely sure, I contacted the author and will post another reply when he verifies what's actually the case.
I think I misunderstood the "editor" note referring to "this is completely untrue" - I interpreted it as saying it being illegal was untrue. Thanks for the repeated clarification.
