I don't think anyone really complained about not getting a pint or certainly meant it without being a little tongue-in-cheek.
As for the greater access, that'll only apply to those travelling from the South. Ask the thousands of Reds from Ellon, Inverurie, Fraserburgh, Peterhead, Turriff, etc... what they think.
As far as I'm aware, Montrose, Brechin, Arbroath, etc are mostly all Dundee/United fans.
I doubt very much that it'll have an impact on those who already travel from these towns but you could probably add an hour onto the journey time and as they'll be going through Aberdeen to get there, it'll only make the traffic worse on the busiest day of the week.
