This lite.cnn site is awesome! Text without ads & trackers that bloat the cnn.com site.
I used to do the same with Twitter, but these days there is nearly no difference between the mobile and the regular versions.
Don't think there is necessarily a consideration of byte cost, given the size of the tracking scripts. A few lines to make this manageable on wide monitors aren't prohibitive for those users.
The websites needn't be text only, Reducing useless elements like Techcrunch's content wrap can go a long way to improve readability and accessibility.
