Completely agree, Beryl. While I fall into the category of 'those with easy SC access', I don't want to see the charging options take a step backwards. (Note: My 2011 Roadster is capable of charging at 70amps.)
My X will occasionally be towing - and some of the places that I'll go, I'll be relying on 80amp destination chargers and other sources. Unfortunately, with this new decision, finding an 80amp place to charge really will be moot.
So far I've heard three reasons from Tesla, shared by others here on the forum: Engineering is clarifying (whatever that means), because of a survey of Model S owners (not buying that), and manufacturing made the call. Two of those three reasons were in the same letter. Consequently, I don't believe any of those reasons.
I'd like the truth. If it's a cost issue, let me decide what I'm willing to pay, give me my options. If it's a supplier issue, tell me if I can swap it out in the future at a SC. If it's something else, be straight with me.
Don't decide what I need or don't need without consulting me, especially after I already lost the option of dual chargers.
