Google is making some significant changes to the Adwords Terms & Conditions which gives Google a bit more protection. The changes include allowing Google to test campaigns without notifying advertisers, disputes settled by binding arbitration, and blocks advertisers from joining class action lawsuits.
Many internet companies already have inserted language like this into their Terms & Conditions. So it is not surprising that Google, a for-profit company is trying to better protect themselves just like all of us try our best to protect our own companies
Thanks
I didn't find the right solution from the Internet.
