For example you can read the "android user on an iPhone 5S" article, and he lists all those important limitations of iOS that would definitely turn any Android user away, but says they are "temporary" and inexplicably concludes that iOS is not a worse experience.
"Temporary" because we already know that these are resolved in iOS 8 which is currently in beta. So, yes, you could rightly claim that iOS lacks these features currently- but that would make for an article with a used-by date of a few weeks or months. Like it or loathe it, it's clear that Apple is happy to steal and put their own spin on the major "distinguishing features" from Android-land.
"A worse experience" and "would definitely turn any Android user away" are rather personal judgements. iOS does some things a lot better, and clearly does some things a lot worse. Just because the author's value judgement differs from your own doesn't make him a shill.
Similarly, supposedly they would test all important smartphone releases, however they review each iphone multiple times (seriously, check it out), then some popular Androids and that's it.
This is quite true, and does speak to some bias- at least as far as what the author has a personal interest in, not necessarily a bias in the facts of the article. To be fair, quite a few of these articles were about the chip architecture, which was a rather big deviation from the run-of-the-mill hardware at the time. It was interesting from a technical perspective, regardless of where you sit on the OS fence.
