You don't hear iPhone users begging their friends to get on signal unless they are discussing drugs or sensitive topics. You hear android users ask iphone users to install wtv app all the time.
And I am talking about anecdotes here, but there are well-document events (some that happened this year) that do emphasize what I am saying. I won't share them though because you know... jobs... and that they should be obvious if you are following this conversation over the past decade. What I will say tho is that only one company wants (wants being generous) the other to change their messaging.
> The fact that it can be simple to share high fidelity pictures and videos, but it isn’t just because Apple wants their walled garden benefits nobody but Apple
Irrelevant. iPhone users mostly just want android users to get iphones. Doesn't matter why.
