Wow. This thread is just strange to me.
Let's start with 3
♦. This diamond suit is often going to make 5 tricks in a diamond contract. Playing in a 4-4 spade fit, you'd often make 0 diamond tricks, and you wouldn't be surprised to make 0 diamond tricks in a 5-4 spade fit either (trumps splitting 3-1 and they get a force going immediately). To me, this is the prototype of a hand that I would open 3
♦ in first seat and pass in second seat (though I am not sure the latter is right). Passing in first seat just because we are afraid of losing a 5-4 spade fit seems losing bridge to me.
Now to 3NT. In my view, there is not a single hand that would pass after (3
♦) P (3N) and that would act after (3
♦) P (4
♦). The 3N psych is so frequent, and you have a better chance at finding your best fit over it (partner has a 4
♦ cuebid available to find the right major fit, and you could get out in 4
♣ if needed). Meanwhile, 3N also gives 4th seat the 4
♦ cue to show both majors. In my view, this 3N psych is the dumbest frequently made bid in bridge.
To illustrate my point more:

btw i think the criticism of east is excessive. with 13 points the chances of getting 3NT under the radar are very reasonable, and whilst the undoubled penalty in 3NT would exceed the doubled penalty in 5D, that's because the hands fit very well and because west has such an atypical hand.
Sure it is true that 3N might go undoubled. But so might be 4
♦ or 5
♦! In fact, there are certainly hands that would pass a direct 5
♦ that would act over 3N.
On to the final double. First, pass can't be forcing here. East had a lot of room to make a slam try over 3
♦. We are never suddenly going to bid 6
♦ in order to make it.
Having gotten that out of the way, what does East's pass mean? Surely, most hands that bid 3N and 5
♦ to make would double. So for me the pass suggests either that East made the dumbest psych in bridge, or that his 3N bid was a bit of a gamble - say, QJx Kx AKxx Axxx. This hand is a legitimate 3N bid, a legitimate compete to 5
♦, yet it doesn't expect to beat 5
♥ if the opponents are serious and partner has no defense.
If you think East shouldn't make the dumbest psych in bridge, then the double by West is completely reasonable.
