In the early days, Musk offered to make Tesla superchargers available to other manufacturers in the hope the EV industry would quickly move to a uniform standard. No one took him up on the offer. I had high hopes for Electrify America, given its ambitious rollout plans. It's one of the reasons I've put a deposit down on a Lucid Air as well as a Rivian R1S. However, your comment is the second mention I've seen of very high charges for using EA stations. (I have free life-time charging on my 2015 Tesla. My brother has to pay for supercharger use with his Model 3, but he has driven it from Atlanta to Naples and been charged less than $30 for the ~650 miles.) When charging my Tesla at home, my energy costs for driving it are about one-third of an equivalent ICE vehicle. It it's going to cost as much to drive a Rivian on trips as an ICE vehicle, one begins to wonder what's the point. Yes, there are other advantages of driving an EV but, as you pointed out, there are trade-offs with things such as less availability of dealer support and repair/maintenance. Taking lower fuel costs out of the equation changes the cost/benefit analysis somewhat.
