Listen, no one is going to defend these excesses of capitalism, the tracking the increasingly user hostile designs, the anti-competitive consolidation and rent seeking behavior.
But seriously, you're going to take research into actual human-machine interfaces and boil them down to "implant that lets you buy toilet paper by blinking"? I mean maybe the entire field of computing goes ethically bankrupt, even if the walled gardens and coercive algorithms win forever, the concept of a computer as a "bicycle for the mind" falling to the wayside as computers become only used as a tool for control. Assuming that you have no faith that anyone will ever use it to build a "bicycle for the mind".
Even if you assume that it will mostly be used for Evil commercially it can still be used for dumb prosthetics and increase the quality of life for a lot of people.
