>Google doesn't fingerprint browsers like other adtech networks do
Citation needed :)
I'm taking part in the Browser Fingerprinting Project that was on here recently[1] and the only browser that isn't marked in the test as trackable so far is Firefox[2]. They don't use cookies for the test so third-party cookie sandboxing or blocking is irrelevant. If Google doesn't use browser fingerprinting as you say then they really should fix Chrome.
Google definitely does browser fingerprinting. I have been running bots for years to collect pricing data. They check your gpu, bunch of stuff from navigator, etc. The only thing I have not seen them do is canvas fingerprinting.
They claim they do not use fingerprinting for user identification for advertising. Some people would say that this is a weaker claim than not using fingerprinting.
They have admitted to using those sorts of information for fraud detection to detect fake ad clicks, bulk account creation, or other malicious activity. I also suspect they do some clustering on this data to determine what accounts are related so if there is malicious behavior from a cluster of accounts that appear to be the same user they can act on the whole cluster.
But there is no evidence that they use fingerprinting for targeting advertising.
