> Libra is invite only and they invited their business friends.
That's a big assumption. They were able to get their business friends to sign on, probably because they are already friends. I'm sure they asked a lot of other groups that were more hesitant, it would have made the initial announcement much more powerful.
Also important to note non-profits, NGOs, and universities are included, and they don't have to pay the $10m buy-in.

The way Libra is designed, that would probably be a lot more trouble than it is worth. Tracking methods without direct trackers (like 3rd-party cookies) work because there are many data points. Like in browser fingerprinting, you have user agents, JS feature availability, history, etc.
With Libra, you only have an account address and transactions to other anonymous account addresses. One dimension of data like that would be very very hard to trace back to the user, without direct participation from many many merchants.
> There's also the wrongthink aspect.
Fair, however afaik only 1 of the 28 current companies (Facebook) has this attribute.
