b) The customer's domain is one of the hugely expensive UK.COM pseudo-TLDs. UK.COM has been reported as being spammy; I assume due to bad apples amongst a high number of otherwise ok subdomains.
And a failure (at least historically...) of the operators of uk.com to accept responsibility for the misbehavior of their customers. They can call themselves a TLD all they like, but that does not change the fact that they are NOT a TLD.
My suspicion is that google is delaying the mail based on the reputation of the generic UK.COM domain name. Is this likely?
Yes.
Is google really dumb enough to treat all UK.COM subdomains as part of the same single domain?
LOL, Yes. Why would you think otherwise? Any large organization is as dumb as its dumbest member. Google is very large and simple probability assures that regularly the organization will do something stupid because they have so many people capable of doing stupid things.
If so, given they allow spammers virtually free range to send FROM gmail this is a bit hypocritical.
It may seem that way, but it is illusory. The problem isn't that they miss a larger fraction of the spam people try to send though them than most smaller operations, it is that they are so damn huge that even if that's 1% of what is attempted, it's a mess. I have looked closely at what actually comes out of Google, Yahoo, & Microsoft on a few different receiving systems, and what I see is that for normal target addresses in use by humans, Google and Microsoft each consistently have a better ham/spam ratio than the average. They are not as clean as most small senders of legit business and personal mail, but they are far better than the bulk of senders (bots that only send spam) and somewhat better than the bulkiest senders (low-end ESPs.)
