Skeptical. I've been using Bing as my primary search engine for awhile here and haven't noticed any changes of late. When I can't be bothered running a VPN, it's the only foreign-language (ie. English) indexing search engine with reasonable results that is accessible (Duckduckgo and Google are blocked). For all the problems, Chinese internet has its perks though: we have many great, instant media streaming services, pervasive mobile payments and Taobao!
