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.
