To be clear, LE won't get Cellebrite's tools because they don't trust themselves to use the tools properly, but LE demands key into all companies' systems and claims they can be trusted to use those kes properly?
Law enforcement is not a monolithic entity. Your municipal police department or county sheriff’s office can barely check its email, let alone backdoor a tech company. However it might be able to get technical assistance from the FBI or a private digital forensics consultancy on an important case.
Clearly the "solution" is for backdoors to be administered by a centralized, "trusted", private, for-profit monopoly! I'm sure VeriSign would be happy to bid on it.
