Well, I think sarcasm is the appropriate response to a top comment that contains no information besides "I don't like this".
He could have told us why he doesn't like this, or give us an example of another company that was acquired by Google where the result was bad for consumers, then at least we could have had a discussion about this.
But this way it's only "I don't like this" vs "I like it" and there are definitely more interesting discussions with more information in this thread that could have been upvoted.
Motorola not withstanding, Google has a history of killing/closing well-loved products (profitability aside).
While I am not upset by this acquisition, I can certainly understand the sentiment.
I can't speak to validity of the top comment being only that aforementioned opinion, nor am I suggesting that sarcasm was inappropriate, but I think this only highlights the upvote/downvote mechanism as an I agree/disagree button more than a add to/ doesn't add to the discussion button.
