Search engines: are they helpers or killers?

If a search engine goes too far, it will cause greater problems. For example: last year's Baidu and Taobao.com incident in mainland China. Because Baidu announced its entry into e-commerce, it directly impacted Taobao.com, currently China's largest B2C website. Therefore, Taobao.com officially announced that it would block Baidu's search engine from indexing the merchants on Taobao.com. This not only shows that Taobao.com is large enough to compete with Baidu, but also represents a counterattack against search engines, as their impartiality may be a potential concern.
