Removing features and dumbing down interfaces means their designers and developers and everyone has less work to do, and they get to make their money from the people too stupid and/or lazy to complain about functionality they don't know is missing.
Which is annoying enough in itself, but when they also nurture elitism to target those who should know better, brainwashing them into thinking it's cool to have less, and encouraging them to infect their friends with their lack of discernment, it gets even more frustrating.
It's been going on for years, and most people are unaware. Even when specific examples are brought up - unless they've experienced it for themselves and managed to resist the delusion that the implementers must know better - they ignore it, suffer in silence, and think those that complain are loons.
