One of the articles says 380 engines are affected, which would mean roughly half the Rolls powered 787s (possibly more, since some aircraft may only have one affected engine).
No first hand knowledge, but given the nature of the problem I would expect the AD to target engines with more than a given number of hours/cycles. It's also possible some new build or recently overhauled engines have a fix and aren't affected.
Airbubba - most local authorities will automatically adopt any AD issued by EASA or the FAA, and I'd expect the EASA and FAA AD's to have the same limitations (they actually do talk to each other
, and they are presumably using the same data and analysis of the issue).
