There is absolutely no evidence that a new waypoint was entered other than journalist speculation.
They have been told by "officials" the WP change was included in the last ACARS transmission.
Other news organizations do not re-report the same afterwards unless they themselves could find an offical to confirm it to them (or the report runs with something like "BBC reports, we can not confirm" thereby eliminating the possibility the re-reporting organization can ever be sued out of existence)
You can only "report" what the experts involved tell you; that is what they are trying to do. Do not confuse "report" and "commentate" though, as those are two drastically different things
