It is so annoying to see that HN and general media have collectively decided that Google and everything it does is evil, but honestly you have no idea how good you have it right now. Google is not abusing your user data like you are made to think. If you talk to a Google engineer, you would realise the countlesss number of measures they take to safeguard user's data - human access is next to impossible. Only machines…
That said, while I agree that Google does not 'abuse' my data by giving it to others in any form, Google absolutely does use my data to try to sell me things. From my perspective, this is abuse. Google is using data that I generated to psychologically manipulate my behavior.
When Google Search, gmail, and other like services from Google were released, Google was a tech company first and foremost. These properties/services were offered for "free". At the time, most people didn't realize that "free" meant paying with your data. Now, Google is an advertising company and I do not want them to have my data because of that fact. In a similar vein, if The Trade Desk or another adtech company provided a "free" email service it would likely not be widely adopted as it would be well understood that users are paying with their data.
