I worked for Google for a long time. I never had a problem working for him or "furthering their agenda" because back then they didn't really have an agenda, beyond doing cool stuff on the web.
The idea that these organisations are unethical doesn't stick. Here's the brutal reality - people care about privacy from the people immediately around them. They value Incognito Mode because they want to hide their browsing history from partner/friends/family/etc. They don't value encrypted email because they assign a value of near zero to hiding messages from Google.
And why not? Privacy leaks out of these organisations are so rare as to be non-existent. They control their employees access very tightly and I can remember exactly one case of a genuine scandal involving a Google SRE maliciously accessing accounts. For a company coming up to 20 years old that's a good track record. Moreover, it's convenient to trust a large corporation. They will help you if you forget your password instead of saying "sorry, no key no access". They back things up for you, give you magical search functionality, filter stuff for you, show you useful stuff. And it costs you nothing! It's a deal so great everyone takes it.
The day I really came to understand that whinging about online privacy was just a crappy form of journalistic champagne socialism was when I took part in a system that showed me how much money advertisers were spending in the auction to appear on my screen during an ordinary few days of browsing. I saw that data because I was interested in the idea of letting people bid themselves out of seeing online ads. It was a staggering amount of money. Many many multiples the cost of my cable TV/internet subscription. Even as a well paid engineer I'd not have considered actually doing it. And for people on a more average salary? Trying to get rid of online ads or making them less efficient would just mean they couldn't afford to use the internet at all. I came to realise that no people would ever agree to pay for the true cost of their own web browsing. It was well targeted ads or it was no web sites.
Since then articles like these moaning about the evil ad-driven tech industry just make me roll my eyes. Don't like it Ms Journalist? Get rid of all the advertising and sleasy agenda-driven copy in your own industry first, then lecture others.
