Vast majority of users are not technically literate enough to know what is a good browser. They would have no clue why Chrome is better or not. They definitely don’t know what Blink is.
Monopolies usually don’t maintain their status because they are “the best” and as if consumers also are informed enough to know that. Similar arguments can be made to allow basically all of big tech.
In a better system instead of talking about allowing everything as if corporations are precious individuals, the govt should be creating funded competitors and being much more firm with monopolistic behavior (even if they aren’t legally monopolies)
