How about whoever wants them to enable them?

  That's up to your editor, the font doesn't get to choose what the default is.

  You are taking this backwards. - there are more fonts without ligatures than there are fonts with ligatures. - every single OS I can think of include by default a monospace font that do not support ligatures. - there are still a huge amount of terminals which do not support them. - for almost any font that has ligature there is a variant without ligature - there is virtually no way to end up with ligatures without actively looking to get ligatures. - any terminal/editor that supports ligature has a setting for that. - most people do actually like ligatures which is the reason they use those editors/terminal/fonts and want those activated by default.
