Because you're acting like it's Google's responsibility to provide a client in addition to a server. This is not the case. In fact, the two are barely related.
Or perhaps because it's kinda silly to say, "Oh, you gave me one thing? Now give me another thing!" It's just . . . a childish perspective? I'm really not sure how to describe this.
Is it not in Google's motivation to make Android the best phone platform it can be? The lack of native CalDav sync irritates me (the app/plugin listed works fairly poorly, from my experience), as well their horrid excuse of what they call "Exchange" support on Android. If you aren't using GMail, they make it very clear you are a second class citizen on Android. Part of the reason I left it after using it for a month.
I'm not acting as if it is Google's responsibility to support any protocols at all. It's just curious that Google would implement a protocol on their servers but not on their operating system. Am I demanding anything? No. I am blaming anyone? Not at all.
The personal attacks based on your perception of my comment are frankly unprofessional and completely unnecessary.
I didn't make any personal attack against you. I answered your question about why you were getting downvoted by describing what your comment sounded like to me. If you didn't want to know what people thought about what you said, you shouldn't have asked.
