It's quite disputable that google even has the right to a platform of anywhere near their current power and influence (waiting for antitrust law to be enforced) and the distinction in any case seems quite artificial when google buys politicians and receives significant public funding and such.
Google does not receive public funding. By your logic, a $2-off a $10 item coupon is me receiving $2 from the store. Strange how I don't have a new $2 in my wallet - in fact I seem to be missing 8.
