you know I feel like there's some people so disillusioned with everything that they automatically assume that the only way to go forward is to try and work on the least ethical, most evil, nasty tech. There's actual thinking breathing humans that work at this company, and I'm sure that if you asked them if they think this is ethical you'll get a "oh if I didn't take the job someone else would" and "this is how the world works now". there are ways to make money that don't involve purposefully doing evil.
This is why we can't have nice things - people that can't stop to ask if they should, once they've realised they could.
