> trying to circumvent region locked content
Semi-related to this, but they do offer an option to pick between preserving your approximate location and using a broader location.
The example they took in one of the sessions was, if you live in San José, with the first option, you'll get an exit node near San José so you can still get local "content". With the second one, you could get an exit node in Los Angeles.
In practice in Europe, it looks a bit different. I do live in the north west of France, and with the first option I regularly get an exit node in the southwest of France (from Fastly), about 700km away (which is pretty fine by me).
With the second one however, I get exit nodes in Germany and the Netherlands (pretty much exclusively Cloudflare), which can become an issue with region locked content. I had the issue with Prime Video last week not offering me a Tennis match for which they only bought rights for in France.
Obviously it's still early and they might tighten a bit the locations outside of the US, but overall it's definitely quick and well thought out.
Last thing, all your traffic from Safari (and presumably some other Apple services ? Still unclear) whether http or https will be routed through it. Only http traffic from 3rd party apps (Firefox, curl etc) is routed through the relays, which I think is a pretty sensible default.
