I haven't played it yet and won't until it drops in price to peanuts, but no DLC is worth £13.99. DLC was a scam to begin with *snip*
I just bought the whole series of STALKER games for less than £15, including delivery, from Amazon. 3 entire games for more or less the same price as this DLC. *snip*
You're entitled to your opinion, and it's fair to question the amount of content for the price, but for me, at least, there have been plenty of DLC worth extra money. Tribunal, Bloodmoon, and Shivering Isles were all worth it without a second thought, IMO.
And comparing older games to current DLC doesn't make sense. You could buy a used chess set for $5 and use that for the rest of your life. Does that mean that no other game is worth $5? Does paying $60 (or $40) for a game entitle you to permanent content upgrades until the company goes bankrupt?
If you don't like where BGS is going (and I agree with many of your points), then I understand why you'd be disappointed and not want to give them money. But Skyrim, like every TES before, had a ridiculous amount of content. I don't agree with many of BGS design decisions (i.e. what they spend their time on), but I don't think any other publisher is putting out that amount of content for the price. I don't think anyone else even comes close. Of course, it doesn't matter if you don't like that content, but I think they deserve recognition for their incredible scale.
