its because people dont know what they want. Linux has the problem that people want different things, ao theres dozens of distros to choose from.

windows is an example of giving little choice, so people begrudgingly “upgrades” because they ultimately dont really know what they want.

tldr, linux can be choice paralysis. single os is like being forced to drink soylent and only soylent, its got what you need but you might not like it.

not yet, but the wikimedia foundation has been fighting against it expecting that it would be a class 1 site and require it.

ah from shady porn sites, like spotify and wikipedia. definitely protect kids from porn there. /s
