FWIW, the argument that they created the system blah blah blah is an outright lie. The original CCS spec was published about a year before the first supercharger stations opened, and both CCS and Tesla are based on the same basic underlying electrical standard. Chademo was introduced back in 2009 (though it wasn't formalized as a standard for a few years). The supercharger system also isn't particularly special in it's technology. Now, in those days, there wasn't a system that could have been called an accepted standard, but the idea and the technology was already out there and either in development or in limited use. Tesla deserves credit for aggressively building it out, nothing more.
But anyway, this is a good move for the greater goal of clean transportation adoption. It'll make it much more practicable for those of us in condos and apartments to have EVs before our complexes/buildings can retrofit themselves (where that is possible at all). Though I don't think the question of whether always/usually charging via DCFC is bad for the batteries has really been answered.
