You could say that about alot of businesses, loads of massive companies would have laid staff off if it wasn't for the furlough system, and loads will no doubt do that when it stops, and many will go bust further down the road even after been allowed to open up in the coming weeks, people are wanting to deny football to do the same and protect revenues a bit, the reality is the money runs out very quickly when the going get tough no matter what the business.
What has changed after 2 months? Well the virus is clearly on the way down, for how long is anyone's guess, but lets say football wrote this season off and prepared for next season as usual, then we get hit by a second wave in October, they'll have to close down all over again, and will have just missed on a potential 3-4 months window of opportunity to play some games, and the most obvious other change is testing, players will know exactly where they are with virus, where as everyone was guessing before the lockdown, it's not perfect, and not without some risk, but that's as good as it is probably going to get for a while.
There are no real issues with integrity, other than people trying to complicate or be uppity about things, it's a once in a lifetime event, and people seem to think there should be a rule book to follow, all industries just need to make the best of a bad job.
