Also, I guess this is proof to some extent? First question asked -

Until now, we counted all people who died that tested positive for COVID-19."
Even if someone had "facts" proving a hospital inflated their numbers, it still wouldn't prove all hospitals or most hospitals are doing it. You're essentially telling someone to prove via facts the unprovable in order to back up an opinion (claim). There is supporting evidence (linked above) for their claim though.
I don't know what to think, maybe some are inflating, maybe their not. Some hospitals that are in bad shape financially may be gaming the system to get additional funds. That is the only reason I can think that some facilities would artificially raise their numbers. Blind faith in any institution or government or organization is usually not a good idea.
