I thought the same and for the first year I didn't buy the CHAdeMO adapter. When I finally broke down and did it I was convinced that the CCS adapter from Tesla would be out the day my return window ended. But ~50 charges later the adapter was all paid off (I visit a lot of power company free DCFC stations). I have now had the adapter for more than a couple of years and that has been a LOT of free fast charges. If I had free charging at work I would use that, but I don't. Sounds like you can't charge at home and I have a few friends in that boat, but where we life they can at least use local Urban Superchargers. If you can get by with the adapter where you live it'll be worth the investment, even if the CCS adapter does come out eventually you will STILL be able to use the CHAdeMO.
And I am thinking the REASON the CCS is still not out is because Tesla is working on the opposite adapter, so people can plug their Mach-E into a Supercharger. Why not stake a claim to making the Tesla plug the US standard. It's the best plug out there and if they had adapters others could plug and charge even on cars that never supported that feature before.
