I wonder what made them change their minds? Was it the advertising going to Facebook instead?
Even Facebook never fully supported advertising of cryptocurrency through their platform, but overtime, they realized that theresabsolutely nothing they can do about it as influential as they believe, even the ban could not have any effect on the adoption of cryptocurrency and instead of losingrelevance to other competitors, and they would rather join in the race too.
I guess that is exactly the pattern Google is also following, now that Facebook is also planning to develop their own coin, dont be surprised that very soon, we will see Google coin campaign all over the internet, I can bet that they are working on something.
