The risk that Tesla sues over patent infringement stands alone of any tit-for-tat infringement. Realistically, it's much more likely Tesla will just sue for $ rather than try and make a counterfeit of an infringer's product. No sane counsel would let their company knowingly and openly infringe on major patents like this.

The spec being open put up on a website does practically nothing. Patent's are public and it'd be trivial to reverse engineer a charging standard anyway.
