Um--maybe the corporation licensed to provide electric-car charging using CCS attachment plugs or that otherwise holds the (patent) rights to the CCS plug pattern? Is that even a thing? Maybe what I said doesn't make any sense, and/or the CCS plug is not licensed technology? If so, sorry.
But
if Tesla could just start manufacturing (cost-effective) CCS-to-Tesla adapters without having to pay somebody for the rights, why aren't they doing it? Should be a simpler and cheaper device than the ungainly and expensive CHAdeMO adapters, right?
Maybe it is not the CCS plug (patent/license) itself that is the issue, but rather the permission for Tesla drivers to actually pull in and use the (non-Tesla) CCS-outfitted charging sites? But that doesn't make sense. Charging companies that use CCS plugs should
welcome Tesla drivers in order to increase their revenue. And most Tesla drivers will probably continue to favor superchargers, correct?
So just what is the problem?

As of today CHAdeMO adapters
still available from Tesla.
