The network effect is the phenomenon of "all of my friends are on Facebook, I better join Facebook," or "all my follows are moving to Bluesky, I better move to Bluesky".
A service has "network effects" if it gets more valuable as users join it. You joined Twitter to talk to the people who were already using it, and then other people joined so they could talk to you.
So you're saying that since a company is reprehensible in one area, all their other accomplishments should be judged accordingly?
Makes sense to me.
