LifeinAsia - that's one of Google's problems, they only test in aggregate and don't care about individual users. For the millions (or more?) URLs they tested there was likely a small CTR advantage to doing lower case. In their thinking "overall" it makes them more money to force lower case. If advanced users that actually test this stuff get shafted...they don't care. As long as they are making more money they are happy.
It's like testing a million websites and finding that overall a big orange BUY NOW button gives the best conversion rate. To their thinking there's no reason to test individual sites, just slap the same button on every site and you're done. I think it's endemic to Google employees' way of thinking. They only see in aggregate, not individual sites or businesses.
