Thanks much for all the comments. It is clear that Tesla is trying to hold control of the EV market through charger control. Again thanks for all the info.
I wouldn't classify it as that sinister. Tesla built their network using a proprietary plug, which was a bit of a gamble initially when Model S arrived on the scene. At the time, CHAdeMO was the most common public DCFC but they saw that as awkward. CCS was being standardized at the time, but Tesla knew that to promote EV sales, they had to build a network.
They have paid for it all, claim to have offered to allow others to use the network provided they comply with a variety of requirements. One requirement was car makers helping to pay for building out the network. Nobody bought in, CCS became the defacto standard, and Tesla just kept moving forward. At this point, while maybe not an ideal situation, we have two incompatible networks that mostly meet their owners needs. It will probably remain this way indefinitely as there are costs associated with change.
As public funds are being pledged to build out networks, the politics are going to be interesting. Subsidizing Tesla charging, exclusive of all other brands would be a hard sell. Tesla owners are proud of their "superior" solution, but as the numbers climb and queues grow at SC sites, Tesla is going to need to add plugs and sites to keep up with growth.
I kind of expect federal efforts might step back a little and deal with site infrastructure needs such as grid connections and local storage, as well as site availability such as federal highway right of way, rest stops, etc. Then, allow companies to bid on installing chargers at the locations, with maybe some cost sharing. In this arrangement, it would be possible for both Tesla, and CCS networks to install plugs at the sites with some financial assistance from DC. That would probably sit well with the public, it is not favoring one over the other.
If Tesla falls behind on site installs, owners will flow over to the CCS\CHAdeMO sites. That might also put pressure on Tesla to adopt native CCS charge ports like in EU. In the long term, we need enough plugs for both, and it is a bit more complicated by the incompatibility. But, it could work if both Tesla, and CCS networks keep up with demand.
