From that aritcle: “There will of course be engagements in the future in which hand holding and affection is perfectly acceptable, but tonight, in the presence of the Queen, the couple showed the dignity and respect such an occasion affords.” Sure. They can explain it away like that. But just the fact that they even felt like they had to explain says a lot. People are noticing that something’s different and something’s off. You can’t go full on tentacle hands and then suddenly stop.
