When they threaten to sue Youtubers who are educating people on how to repair their devices
When they lobby aka payoff governments to prevent right to repair laws
When they refuse to release tools and information that allow owners access to their hardware
When they refuse to acknowledge hardware design flaws or stand behind their products...
I could go on but the point is the idea that Facebook makes unethical decisions but Apple does not depends on what one considered ethical. Walled gardens to me are unethical so i do not buy products in walled gardens.
Like wise I do not accept having my data sold as a commodity so I never joined facebook. They likely have a shadow profile on me, which I do find unethical, but most people are complaining about them selling data they themselves gave to facebook in exchange for a free service, I do not find that to be unethical. People that created an account with Facebook, for free, should have suspected this.
