if i'm paying for a digital subscription, there's no reason why i should also have to look at ads.
i can see why there are ads for a print edition, due to printing costs, paper, and shipping, but none of those exist for a digital edition.
Ads are where magazines make money, not the cost you pay for it, it is just one of those sad truths about the writing business. The cost you are paying is hardly covering just the distribution cost for the digital version (it does cost to produce a digital edition). It would take 2-3 times the price to have no ads. And in magazines like Wired the ads are actually relevant and interactive.
