A lot of people write nice things about Apple (I even think they've executed exceptionally well with great products). Walt Mossberg, for example (even Josh Topolsky is generally 90% positive on Apple -- but also likes Android). But there are many evangelists who write almost exclusively positive things about Apple and furthermore attack things that threaten Apple.
These evangelists maybe cordial to WP or WebOS, because they're no threat, but ICS -- they'll save their best faith-based sermons for it.
I dont think its because they think it threatens Apple (let's be honest, Apple is going from strength to strength).
I think it's because they've been making this same criticism since Android first came out, and its UI is still laggy and stutters. It's starting to look like that is just a permanent feature of Android, rather than something which should be fixed "soon".
All their criticism boils down to this one thing: that Android doesn't have the same level of quality when it comes to UI interaction. They readily say nice things about the features, but the interaction model is still broken, and they keep pointing it out because its important to them. Its important to lots of people, and thats probably why the iphone is selling so well.
Its obviously not important to people who prefer android, and thats fine. But since its not important to them they don't understand the criticism and ascribe people's love of the iphone to "faith" and "evangelism".
I think that's unfair. While WP7 obviously is derived from the 'physics based touch screen phone' category that the iPhone defined, it's also true that Microsoft took it in a different direction that genuinely looks different to iOS. They bet the farm on new design.
A lot of the criticism Apple followers have of Android is that it feels like a 'good enough' iOS alternative designed primarily to prevent Apple achieving dominance. Having lived through the 80s, many tech enthusiasts are keen to see a competitive industry with a focus on quality, design and innovation. Google facilitating Samsung producing iPhone knock-offs doesn't seem to contribute to that.
