IO540, there certainly are lots of pilots just doing their thing, without never consulting neither weather nor notam's nor the holy virgin neither whatever. But I have never observed such behaviour to have any relation to age or internet capacities, to these eyes it seems more related to temperament and education. Not to mention budget.
And both excess of temperament and lack of education are more common among youngsters. Large budgets do seem to come with age, though.
The clown of the opening message seems to have suffered from an excess of temperament. No excuse, certainly, I heartily agree with O/P. But there is NO illustrated relation neither with age nor with internet currency. At the contrary, without internet information said clown might never have known about the event and gone blow his whistle elsewhere.
