Never heard of them.
Their main focus is end-to-end encrypted email. When sending encrypted emails outside of their ecosystem, they used to send a link to a temporary account, so as to reduce the chance of a leak.
They've never been hugely popular, but their name pops up a fair bit in circles where legality of things might be a bit gray. Like countries where certain human rights are suppressed, or where Tor is needed to workaround only getting government approved sites, etc.
Never had an issue with them personally.
Palantir? Facebook? Google abuse user data for profit, but at least:
a) their goal is only money
b) they don't leak that data left and right, and don't leave themselves way too easy to be used for inciting genocides
Facebook is by far worse.
what do you imagine targetted advertising is? they will sell everything they know about you to basically anyone willing to pay in the form of "I'd like to target these particular audiences in my ad campaign", and then when you get conversions from that particular campaign, it's not exactly rocket science to dereference the click to a particular individual, provided that there's a conversion.
and if you're a bit more nefarious than that, you don't even need a conversion.
If Google is a chartered fishing expedition, a data broker is a fish market.
How?
What alternative mail hosting provider do you recommend? Google? Microsoft?
Google, in my humble opinion, is the single biggest evil in the digital world today.
