It is not just breaching the privacy of the users and profiting from it. Facebook is behaving more like a political entity rather than a social media channel nowadays. They have taken an extreme-left political view, and constantly delete posts and groups having a right-wing tilt. Back in 2016, they tried to sway the POTUS elections in favor of Hillary (and failed miserably in it). If they continue to involve in politics, then the users should start boycotting their services.
You spotted it very well. They have started behaving very politically lately and though there are talks about freedom of expression, your comments get deleted within minutes depriving you of your basic right. However, the company has a great influence around the world and the quest these days is for data which is the best thing that has ever happened to Facebook. Facebook can make use of the data in numerous ways.
