The decision to use a signal knockoff was a planned and managed one, not just on a whim. Who's responsible for managing the phones?

It's not really a knockoff, it's a deliberately cracked version of a B2C app to adapt it to a corporate setting

[Zak]

The Signal client app is open source; it's probably not reasonable to describe a modified version as "cracked". Signal does discourage the use of modified clients for security reasons, but does not actively block most of them.

Don't speculate, the evidence is bad enough.
