its like what the old east german people said after the wall fell. i forget the exact phrase but its something like: "before, i could criticize my boss but i couldn't criticize the government. now i can criticize the government but i can't criticize my boss"
I agree that is a problem, particular with the concentration of power in small industries and the cultural homogenisation of people in power.
I recall in 2016 British employers who said they would fire any employees they discovered voted for Brexit - of course the only way they could find out is if people said how the voted but that is a free speech issue.
I think we need legal protections for things like free speech that we have traditionally had against governments to apply to employers and service providers. I think legislation that prevents various forms of discrimination proves it is achievable.
