That sentence says more powerful, not most powerful. I do believe Goldman Sachs is the more powerful institution of the two we've been discussing - listing off other influential financial institutions doesn't really support the counter-argument. Google is also one amongst heavy tech companies such as Apple (arguably the most influential tech company since it has the most capital, not because it has the highest market cap), facebook, etc. Goldman has influence worldwide. Google can hardly go 6 months without a billion dollar fine from the EU. Google lags behind Baidu and Soso in China - these institutions are just not in the same ballpark.
