To play off the Linux mention by the OP... reminds me of SSL certificates, which I always thought was a similar scam (rich get richer thing) to scuba agencies. Basically a few select organizations get this power to issue certificates, and the requirements to start your own organization are so great that they don't fear any new/real competition. In the diving world the names would be PADI, SSI, NAUI, etc. In the SSL world it started with Verisign and Thawte, but now has finally grown, and we finally have a real free option (Let's Encrypt).
Let's Encrypt is free because of billionaires with various interests in providing the services. Maybe what could happen for diving would be like this: Take Elon, Jeff and Bill on a dive, so they can see how awesome it is. Then explain that divers spend a lot of money and travel a lot, so they should want to track us (analytics data). To enable this, they just need to give dive shops around the world free equipment to quickly validate a persons certification status (thumbprint, facial recognition, driver's license, etc -- with offline abilities or they provide Starlink/Satellite service to remote locations). Then to make sure it is wide-spread, give free certification to anyone with existing certification, and also offer no-fee certification options to dive instructors (making it better for them to use this system vs PADI/others).
In return, the billionaire gets data about every diver that dives from any commercial outfit, since they can track each time your certification is checked. Now, next time that diver goes on Scubaboard, Facebook Google, etc -- they can target ads to that person related to their travel history/etc. Down the road, once they have enough power, they can also start to change the rules -- make dive shops run a registration check for every purchase (it is super easy, so why not?), and now they get analytics about every purchase every diver makes also, not just trips/dives they make. Bill especially might like the potential "green" options -- having this power could maybe start to let them control who dives where and when. "Sorry, you used up your 3 carbon dive footprints for this year, you have to wait until next year to get within 100 feet of a reef again."
Personally.. the system is horrible, but every time something changes, it just gets worse.. so keep it as is, for as long as possible.
