The Google explanations didn't sway some critics.
Google has attempted "to weave and spin this critical issue," said Jeffrey Chester, a frequent Google critic and executive director of the Center for Digital Democracy, a privacy and open Web advocacy group.
The issue isn't as simple as Armstrong's posts suggest, and Yahoo's decision to turn over a core part of its search functionality could leave the company "fatally wounded," he said. The deal also raises privacy concerns, Chester added.
"Yahoo's future, in my opinion, as a full-service online ad company is endangered, as more businesses realize that its search ad business relies increasingly on Google," he added. "Google should have been able to acknowledge that a major deal with its leading search competitor raises serious questions worthy of broad debate and critical analysis."
