I think the "blurred lines between editorial and advertising" argument is overblown, since the magazine's writers and editors aren't responsible for selecting keywords or implementing IntelliTXT.
A better reason for discontinuing IntelliTXT links is to remove a major annoyance to readers.

They are still keeping IntelliTXT on all the non-article pages (such as company profiles).
