It's interesting, but at this point I question every "spontaneous" anonymous post trying to discredit any mitigation as soon as it starts to gain traction. 

It's all just too convenient, and there's too much money riding on convincing the public there is no problem, so they don't need any precautions. Again- trillions in commercial real estate, in-store retail sales, movie theaters and restaurants. Any public display of precaution or prevention is something they have to nip in the bud.

If a lot of people start testing, the public is going to say, "Should we have access to testing?" or "Should we have one of these at the office?" and those are very, very expensive questions for them to start asking. 

Those are the kind of questions you hire consulting firms to keep people from asking and launch astroturfing campaigns to stop.
