This is an epically bad decision. Tesla will regret this. This decision is ONLY a negative for all current Tesla owners AND future Tesla owners.
SC network is already unable to keep up with the Y/3's coming onto the road. The SC build out has been way slower than planned. So now Tesla owners have to share those limited spots with Nissan Leaf's and whatever else crap out there?
Alienating Tesla owners is not a good move. There is not a single positive to this decision for Tesla owners.
There are two main reasons why Tesla was ahead of everyone else:
1. Tesla SC network making it relatively easy for Tesla owners to charge on trips.
Now they've removed one of them. Now I am seriously considering changing my Cybertruck purchase to a Rivian R1S. Since now I can charge the Rivian at SC's and the Rivian has room to sleep/camp in unlike the Cybertruck.
Once the SC change happens, Tesla forums will be flooded with people waiting in line for slow charging non Tesla vehicles taking up spots. You wait and see.
