What they mean by "change the damage calculations of tanks"?

Vitality isn't a "Tank" stat, it simply gives you more health like it does everyone else. It does not reduce your damage in any way. The way this game works is you only need enough health to "not be" one shot so your healers can keep you topped off.

Tank A in VIT pretty much means "Lazy Player." They can clearly see what the two stats do and chose the one because it makes it easier for them. When going STR makes the fight shorter and makes it easier on the entire party.

You may not believe Vitality is a tank stat, but SE certainly does, why else would be the only main stat on Fending accessories.

Tank A in VIT does not automatically mean lazy player, or that they are making it harder on the group. I will give you a very real example from just the other night. FC invited me to help with an A1S clear. 5 players are on A4S, there are 2 new people to A1S and myself who was on A3S. Since I'm a drg, the other drg on A4S ran War. We proceeded to wipe I don't know how many times that night, probably 40-50 times in that 2 hours. Why did we wipe? Because the War tank had 13.5k HP, wore full slaying from his drg gear, and the one new healer couldn't keep him alive. He died to everything possible at one point or another, and the 2 people we tried to get clears for didn't get their clear that night.

According to your logic, he wasn't being lazy, he wasn't making it more difficult for us to clear. When in reality I can very well argue that he was being lazy by refusing to put on a few fending accessories to give the healer some breathing room, and he wasn't making it easier on the group by wearing slaying accessories since all that extra damage went to waste laying on the floor.

It's not so black and white.
