It's nice when Google does things that benefit a lot of people, but they're a for-profit corporation and not motivated primarily by altruism. People might not fully understand that or its significance and simply enjoy Google products, but I think it's useful knowledge.
Because that's the part I'd find hard to believe.
My takeaway was that many people produce warm feelings about an entity that doesn't necessarily reciprocate or find those warm feelings important in it of themselves.
I personally like Google (so far). E.g. I could have seen them siding with ISPs, trying to dismantle net neutrality, and using their capital to stifle innovation keeping them at the top.
But if sometime in the future, Google enacts policies that aren't so "nice", people may do well to avoid confusion by remembering that Google isn't inherently "nice", but they are inherently "for-profit".
