Is Baidu Security Center, which challenges 360, trustworthy?

Today, on the blog of Stars' Home, I saw this article introducing Baidu Security Center - "Baidu Security Center: A Challenge to 360". I used to know that Baidu launched an online antivirus service, which is the Baidu Antivirus Channel that has been gradually forgotten by people (personally, I think it's an extremely failed service of Baidu). Now there's a new Baidu Security Center, and I really can't figure out what Mr. Robin Li is thinking about, why he wants to meddle in everything~
