Microsoft vs Microsoft (or to be more exact: IE6 vs Hotmail)

http://www.swelltech.com/news.html memuat info tentang ketidakcocokan IE6 dengan Hotmail.

Recent changes at Hotmail.com and within IE6 has led to some users receiving a blank page in response to a login request when browsing through a proxy operating in interception, or transparent, mode. This is due to Internet Explorer 6 sending a syntactically incorrect Accept-Encoding header for requests to Hotmail.com.

Jadi siapa yang salah? Microsoft atau Microsoft? :D
