You have absolutely no knowledge that this is why people haven’t switched, indeed it’s highly unlikely that it would have been as successful as it has if this were the case. People move to Signal because they distrust Facebook and telegram.
The more logical explanation is simply network effects and inertia. Occam’s razor.
