I've got a Rivian and have only used their chargers on a road trip to Whistler from the Bay Area. One was in Shasta behind a little hotel—you'd not see it if you weren't looking for it. The other was at a Homewood Suites lot somewhere in Southern Oregon. Unsurprisingly, these were back-to-back stops. So, I think they were specifically put there to help bridge a gap between Northern CA and Southern OR.
Agreed. That comment was just a response to the parent who commented that they hadn't seen RAN chargers often.
Of note, right by the Shasta station was a large Supercharger bank, so the planning for this was probably done before the Rivian deal to use Tesla chargers and the free adapter program Rivian implemented. They may have kept that one anyway, considering the Shasta Area is probably underserved and fits Rivian's target market for their stations ("adventure" areas)
