Information “dilution”?

Dynamic Internet Technology released a report on results of Google.com vs. Google.cn searches, but done via a proxy inside China. Not surprisingly, things look different from there:
Besides removing results, Google also adds more results from websites in China to www.google.cn and www.google.com when accessed from China. Those websites in China usually follow government propaganda closely. Because of the ranking algorithm, such larger pool of well inter-connected web pages will “dilute” other web pages and lower the ranking of oversea web pages sooner or later.

So the known Internet world on the mainland will include more domestically produced content than content produced overseas.  Is that dilution?
