No, it won't.
The problem is that the minority channels also get ad revenue. You can get more ad revenue from 6 popular slots and 6 unpopular but specialist slots than you can from 6 popular slots. The purpose of bundling, in part, is to raise subscriber and viewing rates on the specialist channels to the point where ad revenue can be collected in useful quantities. Unless the Swedish Curling channel is bundled, people won't subscribe to it in sufficient numbers, and you won't attract viewers who will be willing to watch the odd curling match here and there but don't like the sport enough to buy a subscription to the channel.
Unbundling, then, is the right wing option, and bundling is the left wing one.
Say 30,000,000 people want to watch a reality show about Kim Kardashian; 300,000 want to watch a film about Kim Jong Un; and 3,000 want to watch a documentary about Kimchi manufacturing, then the last group would have to pay much more per person to cover the costs of providing the program they want - and many might not be able to afford it. But with bundling, everybody pays the same price, and everybody gets to watch the programs they like.
Why are all the people who are usually in favour of this sort of approach, now against it? Normnally, the majority getting what they want and a minority being left out is the sort of thing they are against.
Because unbundling is government regulation to ensure a free and functional market. While right-wingers in theory support a free market, in practice their ranks are swelled by small-government conservatives, who hate government more than they like a functional free market. Similarly, while left wingers like to support minority interests, they tend to me more keen on freedom of choice.
There's also the slight problem that supporting bundling means supporting the right of producers to distort the market. It's not an impossible position to sell, but it's pretty hard.
