The second quote you posted appears to directly support my stance, and that you think it shows my claim wanting throws your comprehension of the discussion into question.

Britannica is not authoritative, it is one view. It attempts to promulgate One Answer, not to capture the breadth of all English usage in all countries. It hedges itself with words like "generally".

I've never argued that the Britannica interpretation is invalid, just that mine is also valid. Nothing you posted contradicts that.

This all is like a French person getting annoyed at a Quebecois because they're using a different word. Or a Spaniard getting annoyed at an Argentinian. Different places use different words differently, and thinking it isn't so is simultaneously arrogant and ignorant.
