The wording in the article's first paragraph can almost be read as if the policy applied to all Tesla cars used commercially, but the actual announcement is more clear:
> This Policy applies to all Superchargers worldwide and all Tesla vehicles purchased, either new or used, whether from Tesla or a third party, after December 15, 2017.
> This Policy applies to all Superchargers worldwide and all Tesla vehicles purchased, either new or used, whether from Tesla or a third party, after December 15, 2017.

I updated the title accordingly.
