The last two times I've been to the grocery store I've gotten into conversations with fellow-shoppers over the red onions. Well, not conversations, really; just brief shared exclamations over the size of the onions DeMoulas Market Basket insists on trying to sell to us. They're really big! So much so that many people are unable to refrain from comment. There actually may be a certain demographic that notices and remarks, now that I think about it: older folks who have been buying onions for fifty years and have a considered opinion about what they should look like. And me, I suppose. I rather enjoy the camaraderie.
And really, who wants a five pound red onion? If you're cutting it to put in a salad or on sandwiches, even a regular-sized onion is more than you want at once. As for cooking, on those rare occasions when I want a red onion instead of the default, regular onion, I expect the replacement to be of a size with what it is replacing. Otherwise my calculations are thrown off! So I don't know what these growers are thinking. They should stop it.
