Apparently for GE it is more economic / convenient to pick up the tab & get it over ASAP, then to explain the NTSB, FAA, public, Boeing, BA, customer base what exactly happened and why for the next 10 years.
This will be the most expensive "repair" to a Boeing 777 ever. Similar to the exploded engine QF A380 repair. That one was less damaged & new.
This paper is also on an NTSB desk. It is better to discuss an aircraft already back in flight, than one on public display in Las Vegas. Common sense.
