Truly a jaw dropping blog post, as the top comment currently states, Apple may be legally required to at the very least, comment on this situation.
"Required" to comment? By whom and for what reason?
Obviously there may be some backchannel, but that is probably how it would go if you assume Apple and Cellebrite have no relationship.
The principles of laches may still apply and provide a defence for Cellebrite if Apple makes an "unreasonable delay".
By stockowners who might not like their valuable IP used in this way or by this company without permission?
This, if Apple does pursue it, is a copyright matter, not trademark.
