I agree completely. Personally, I think the people who confirmed while Alcantara was the only interior shown to the public or on the web, should get some sort of compensation (even if it's something simple like some supercharging credits).T 3) all reservations are refundable, really the ONLY people who could say 'bait and switch' are the ones who placed their order when alcantara was being shown & something else gets delivered.
Everyone after that point can be disappointed, but should not claim "bait and switch"
Having said that, it would be nice if Tesla would remove the pictures all over their site still showing Alcantara interiors in the Model 3. Even the MyTesla log in screen still shows it prominently, which is a bit like rubbing salt in the wounds of people logging in to configure.
