Self-selected (those who choose to answer the poll in their app) sample (7k of 100k) of the population.

More so: 7k replied, 64% against the censored search engine.

Of those 7k a smaller number were Google employees (it does not say the number) and among them 65% approved of censored search.

The 64% against includes entire blind community. Of those working at Google who replied it was majority for it.

Put another way, even though the macro blind community was against. Googlers in said group were for it. Showing googlers are more likely to be for than against

As the GGP said, it's a small sample, and self selected.

You could be right, but this evidence is not conclusive.
