Per the information on the hub.united.com, UA should not currently be allowing passengers to "select" middle seats on flights through the end of May.

However, I've seen flights go out nearly full, even today. By looking at the Standby list, I can see there are passengers assigned to middle seats and they aren't just blocked. It appears they aren't denying boarding to anyone willing to take those middle seats. Does anyone happen to have any information on how or if this is being enforced? Curious more than anything else.
For example, you can look at UA2334 | PHX -> ORD | 5/4
