My sister works in manga and anime publishing and this is an existential threat to her company. Some of the issues they're grappling with:
1. For some of their titles, the genuine item doesn't even appear among search results on Amazon—only the counterfeits do.
2. The quality issues with the counterfeits can result in losing all future business from a customer. For example, download codes will be missing or non-functional. Irrational as it is, customers blame the publisher when this happens and stop buying further titles from them.
3. Amazon seems to be using some slapdash ML to determine how many of each title to order. They'll purchase 10k of vols. 5 and 7 of a series and only 1k of vol. 6. Guess how many of that 10k of vol. 7 end up selling when that happens?
Amazon is, needless to say, non-responsive to their concerns.
In the past month the SEC has stopped most enforcement actions involving crypto.
That's it?
This is not remotely true of analysts and data engineers, who probably write most of the world's SQL.
What's the theoretical significance of the 2/3 threshold?
No. See "A read-only transaction anomaly under snapshot isolation" [1].
Implementing any functionality over two billion devices is non-trivial, especially when it requires aspects of transactional behavior (as this would).
