with current situation it seems they are preying on fear !
if they can produce legal studies that definitively prove their claims then they will have no problems.
however i doubt their claims are true or they would have produced the documentation and not get sued.
preying upon people’s fears especially with a global pandemic providing a reason to be honest and not endanger people then i hope the govt shuts them down and takes 100% of the revenue they made from sale of products and gives it to hospitals to,help prepare for next pandemic !

sadly if the govt ever did this the money would never reach any hospital but go,in general fund and blow it !
