Hmm .. the author uses a hotspot connected with a SIM. Their whole argument hinges on not being tracked, but their hotspot is with them all the time. Seems like a massive hole in their privacy argument.
Android phones automatically randomize Mac addresses.
Although, if you are on Google's Android, it is possible for Google to keep a list of all Mac addressed used and then work with the hotspot owner to find out your whereabouts.
Not always. Where I am, for example, it's law to KYC users of wi-fi hotspots, usually by phone number. Good news: there are a lot of places that don't bother and just have the wi-fi behind a password. Bad news: whether you find such a hotspot is very inconsistent, even within the same chain. So I don't bother and just always use my phone as a modem.
Also, apparently bypassing authentication may be as simple as stealing the MAC address of someone who has already KYCd, but that sounds like it would be even less consistent.
For not much more than I pay for my (definitely throttled) mobile service, it'd seem like a fair trade between the two. With certain considerations given to service availability and local network speed.
There is even a pixel phone given to members of certain memberships.
Something I wanted to make easily available to anyone passing through here.
I used Calyx Internet (the lowest tier) for 3 months. I get like 25-35 Mbps most of the time.
BUT like occasionally, you get dropped to less than 5 Mbps for like hours or perhaps an entire day, and when it is experiencing its low speeds, sometimes my deprioritized cellular internet is still slightly faster. Basically the point is: It's not exactly a home internet replacement.
There is even a pixel phone given to members of certain memberships.
That's not really a membership. You pay $800 upfront for the first year of the "membership", and then its $5 per month for subsequent years. Its just a nice way of wording a phone purchase. Its completely separate of the internet thing.
