None of these seem like real complaints.
This is bad argument. What constitutes a "real" complaint?
Requiring Battlenet accounts for each copy of SC2 sold
This is how software works in the modern age.
It shouldn't be.
and no ability to resell SC2
Just don't put other games on the account you use with SC2 and you can sell the game+account.
Why should one person *have* to have multiple accounts, just to retain an option they've had since the beginning of the industry?
For that matter, why should someone *have* to have an account at all in order to play?
With WoW it makes sense; the design of the game inherently requires connecting through a central server and uniquely identifying the connector. (It would have been possible to design in a locally-hosted single-player mode, but it wouldn't have made a lot of sense, and it wasn't done in any case.)
As historical network play has demonstrated in past Blizzard RTSes, the game design does *not* inherently require connecting through a central server, much less uniquely and permanently identifying the connector.
no ability to hold large LAN events without cooperation of Blizzard
I don't see that anywhere. Blizzard will try to sell "LAN party services", of course. But you can organize whatever games you want however you want.
I think he's talking about the fact that, if Battle.net - or even this particular incarnation of it, which includes compatibility with whatever exact protocols the game speaks - goes down or is taken down, network play becomes impossible. As long as Blizzard remains a going concern and plays nice, this won't be an issue - but if it ever goes under, or if its data centers go haywire, or if it decides it doesn't want to support the game anymore, then it's suddenly a major issue for anyone who wants to play at that point.
Alternately, he might be referring to something mentioned in the comments on the other recent Blizzard story - large numbers of people connecting from a location which has them all show up as a single IP, and then that IP getting banned for having too many simultaneous connections...
Or something else I haven't though of, in which case hopefully he'll explain.
