I don't think there are many people in the West who profess love for the UAE. But there are several reasons why it's not as disliked. First, it's a monarchy, and monarchies are harder to parse, given that many European countries are notionally monarchies too. Second, it's not by any stretch of imagination a serious geopolitical or economic threat to the West. Third, although it is authoritarian, by most third-party assessments, it's not nearly as authoritarian as China.
People seemingly often forget how brutal Chinese authoritarianism can be. I don't know whether it's the fault of the news or if it's selective amnesia, but there are few worse cases of authoritarianism than the country that welded people into their apartments.
You're giving people too much credit. People in general simply do not care about whether or not a government has committed atrocities, even when that includes their own government, as long as they think (rightly or wrongly (usually wrongly)) that atrocities won't be happening to them.
