Your question is why the landlords aren't publicizing it?
More like news sites.
Matzav / TLS were quick to post the psak saying tenants don’t have to pay - having an effect in many Jewish “landlords”
I think it should also post when they do have to pay.
It’s also good for the tenants to know as well and not argue / go to Rav about it.
(obviously they can still ask their LOR).
Point is - it’s Jewish money on both sides.
