How many people choose a browser, compared to those that use whatever the OS defaults to/pushes on them?
Also, using the OS default is also a choice. If someone uses Edge in Windows, that's a choice.
It's only iOS where users have no choice.
OS restrictions, if any, are not the reason Mozilla is dead in the water.
And yet, somehow, Chrome is still more popular. So what are those horrible tactics Google uses to brainwash people into using their browsers when both of their major competitors use their own operating systems to either harass or ouright force the use of their browsers for the users?

Mozilla is farting vapid air with this essay.
