Our store starting taking all the "expired" protein boxes, pastries, and sandwiches and denying them to the partners under the guise that they would go in these yellow bags for donation. But we found out they were tossing them out in the dumpster in the back, so now we just take them home again. Wasting food when people are hungry is the height of immorality.

I completely agree, but it's worth noting that it's difficult to create an alternative delivery chain on the fly. It's not as simple as "give it to food banks." Most really large dairies don't bottle their milk on site. It's shipped off in tankers to bottlers. If the bottlers are only getting, say, 50% of their usual orders, they're only sending out enough tankers to cover that amount, and the dairies have no way to get milk into anyone else's hands. They can't hold it indefinitely, they have no way to preserve or use it on-site, they don't raise any other animals that could consume it (pigs, for instance), they can't just make more space for it.

It's an oversimplification, but it's a bigger problem with our current industrial ag & food distribution systems than greed. Farmers really, really, really hate to waste product. It's a last resort.

They're doing that in the US as well. It's due to the well oiled supply chain being unable to quickly change how they deliver milk.

Right now there's a major drop in demand for foodservice or institutional dairy (ie. Restaurants or schools). Hospitals and Nursing Homes would be using a little more milk than normal, but sick / elderly people can't drink that much milk to compensate (they were already being served milk beforehand).

As well, packaging requirements are different, foodservice and institutions tend to get bulk packaged milk (bag in crate even), but no one at home can really use that. Dairies are already having trouble keeping up with bagged / jugs of milk for the supermarkets so trying to produce more is much easier said than done.

It would be nice if excess milk could be diverted to food banks or processed into cheese or other dairy products, but there's only so much capacity available.

Furthermore from what I know, milk production tends to rise seasonally right now. In my area, the dairies offer a premium to farmers in the spring / summer generally (via additional quota) so many farmers are having calfs now so they can use their extra quota. It's definitly far from ideal, but I'm assuming the dairy system is producing as much as it can for individuals to consume and the most efficient thing is for the surplus milk to be dumped at the farm to avoid transport requirements.
