Google is neither the 'good guy' or the 'bad guy'. They aren't there to look out for your best interests and we'd all be much better if we stop ascribing human qualities to gigantic corporations.
No other company tracks your online behaviour at such industrial scale as Google - and gets so little scrutiny for it.
For most of the tech community, Google's level of tracking is perfectly fine because Google has never had a data breach (that we know of). That somehow makes everything fine.
When it comes to matters of privacy, there's a lot of hypocrisy from the tech community.
