"Trying to create demand" makes zero sense. "Trying to limit server population" sounds more reasonable, if Blizzard is indeed holding back copies.
I haven't had any real problems on the servers that I've played on (Lothar, Feathermoon, Shadowsong), and one of those (Lothar) is on the other side of the country from me. Those servers that have problems really do have problems though (Icecrown is one of them, I played on it briefly) and if I were Blizzard I'd ban new characters from being created on those until they rectify whatever the trouble is - mainly to keep new players from having that be their first exposure to the game.
I will say that the lag has gotten somewhat worse since New Year's.
