Yes I read about this when trying to verify the OP's sensational claims.
It is interesting but doesn't demonstrate that it's possible to revert an organism to a previous state in its ancestral past by destructively "knocking out" genes.
Whether prior states in an organisms ancestral past are contained in its current genetic information and subject to ordered tweaking in a corporate way seems highly speculative at this stage.
It is surely not demonstrated by the presence of teeth in a chicken with a fatal mutation. To present that to the public as proof positive of the ability to create dinosaurs from chickens is just hype and sci fi marketing.
Of course not everyone jumps to the conclusions of the OP, but probably many do jump to such conclusions by the misleading phrasing and imagery of those doing the marketing.
