This is a good take honestly - Firefox could be perfect and efficient and secure but if the defaults are good enough why would people make the effort to switch ?

What we really need is normalised effort to provide an alternative to the systemic issues you are starting to bring up. Not just the browser market but the entrenchment of big tech in general. An organisation that can deliver on what the idealists individually want in a big, cohesive way.

Personally in our current day an age I think that's what a labor union can provide (in addition to the obvious other resources).
