The freedom to decide when to patch is fundamental. Typically, only those with an urgent need for the patch features become "early adopters". The rest of us wait to see what problems they have (if any).
The adoption of Steam for Skyrim is yet another attack on the freedom of the consumer by an increasingly authoritarian games industry.
Now, some people will say that a company is entitled to do whatever it likes to its customers, but that argument wears thin when there are few competitive products to buy on more favourable terms.
Sadly, the industry seems to have adopted a siege mentality, where repression is seen as a better response than listening to customers.
For now, all we can do is work around this.
I've been told that patching can be by-passed by renaming the game folder before going online. I'll try that, unless anyone here has better information.
