IDG
IDG owns IDC. Its modus operandi is explained in this post and an example of its anti-Linux bias was shown here. IDG systematically uses its publications (masquerading as news) to promote its analysis, expectedly favourable to clients such as Microsoft. IDG itself employs Microsoft staff, many Microsoft MVPs and so on.
