I play War Thunder since it became open beta and I have to agree with Mudzin. In general premium users are people who aim to get a certain high rank plane they would love to fly. They mostly lack alot of the experience that non-premium users gain by grinding through the tech trees. While doing this you get to know each plane and it's strength and weakness much better than just starting and instantly buying a level 10 plane and going HB. Ofcourse there are exceptions from the rule, but in one year of War Thunder you get the picture.
Pernizech won his premium acount and as I played with him a few times I can tell you that he doesn't need this account to be good. It will just help him to earn alot more money and XP alot faster ... that's all.
And he won it with his skill so he rightfully deserves it.
Tbh I can't stand this "Get a job, Hippy"-attitude. If I would have spend 26 euro to play two months of a beta for that limited time, I would have punched myself in the face. Thank god it is not my money, and everybody is free to do with his money as he pleases. But as Mudzin said: in some areas of the world you have to work damn hard and long to earn those 26 euro.
Just a reminder that moral values can vary alot, so you should think about to get down of your high horses.
And no, premium accounts are not always connected to skill, but very often and this inversely proportional.
