We could easily beat them by releasing even a limited run exposition prototype with a globalstar $100 data module integrated into a Pinephone back cover using the pogo pins.
Maybe this is is the TU-144 vs the Concord thinking but we could and should beat them, SPOT messenger has been around for maybe ten years already, this is not new ground except integrating with a mobile phone.
I suppose it is the cool factor and being better than crap brands but I cant watch apple be the only one selling satcom on their phones.
Someone get one of these and a pogo pin ribbon and post it on Hackaday.com

they are still available just not direct from globalstar.
pine devices generally speaking do not need this.
i'm putting my paranoia hat on!
this satellite technology involves two-way communication system for devices, we could be tracked and crucial data sent to unknown whom. and we cannot escape it to anywhere in this planet or is it beyond this planet. apple already collects data and sends it to somewhere, now through satellites. nowhere to hide!
paranoia hat out.
apple's satcom is still two-way, i would rather be without, even though it cannot be used for mass data transfer. separate emergency satellite communicator could be a different thing although only for some specialized cases.
This particular globlastar L-band simplex data service is probably able to be located to within about 100km probability oval by doppler location(is a LEO system) via a bent pipe transponder(no processing on the satellite), assuming they even wanted to do more than convert the received signals, I think the message formatting though has reserved data bits for user-added GPS coordinates. So it is more private to location than mobile phone network, the particular globalstar tech is expensive a $110 modem board, and a cheap plan is $14/mo with 25 included messages again only one-way; it is mostly used to send low speed engineering data for pipelines and similar as well as scientific field measurements like remote area weather station data. I appreciate the paranoia filter, it is one of the steps I take with my tech designs and when considering a commercial option too; while globalstar is expensive for the amount of data possible it is a reasonably no-track option and way smaller than the amateur radio satellite gear I have used in the past.
(edit)
Seems to be confirmed as globalstar https://www.cnbc.com/2022/09/07/satellit...-deal.html
