That's fair, and I don't like their marketing too (and others too, look how the reviewers pushed back on misleading claims in the paper). I was talking specifically on Majoranas being behind sc/trapped ions/cold atoms. If they manage to make 1 and 2 qubit gates and it will have good error rates in couple of years (and that's a big if), they'll be approximately where for example Google is expected to be. And the question what will be easier to scale is very unclear and will decide who wins eventually
