I can't say anything for the Reddit part of what you said but I agree with Google's unethical datamining. It's no secret what Google has been doing. I remember when the tinfoil-hat-wearers were warning people about those nifty little Google speakers people were generously inviting into their homes, telling them to watch what they were saying in the general vicinity of the speakers, that Google could be using them to listen to every conversation. The naysayers said "They wouldn't do that, that'd be illegal. The speaker only listens when I say 'Hey Google' and they wouldn't be saving what I say anyway!". Lo and behold, it finally got leaked that was wrong, that the speakers were listening 24/7 and Google was keeping everything. I could be wrong but I recall something going around that Google even admitted they were keeping the recordings. Suddenly the conversation died down, there was no lawsuit for espionage or any such thing and the naysayers suddenly converted to "I've got nothing to hide, I don't care if I'm being recorded". Ignorance remains forever blissful, it would seem.

Quick note for the pedantic: No, it's not just Google. Amazon, Apple and Microsoft are doing it too. If there's a microphone in your house, be mindful of what you're saying around it; you never know how an innocuous conversation might be used against you.
