I'd like to hear responses from those who work at big companies like Facebook. The media painted a picture that the company is putting no efforts on "managing" political divid or fighting misinformation. As researcher/engineer, I can see that FB/Google spend a lot of money in research in this area (I worked in this area for some time), but I have no clue how does this translate in practice and deploy it in production?. It's a borderline also when someone works in a company where it does make efforts to fight a problem, but it is not succeeding at solving the issue, and work for a company that avoid solving the problem.
