Before Einstein, the ether meant one thing. After Einstein, a different thing was given the label “ether”. So when I say that Einstein disproved the existence of the ether, I mean the original definition.
If you were going to criticize anything, you should have said that Einstein only explained what Albert A. Michelson and Edward W. Morley had proven by experiment in 1887.
