Are you sure about this? From what I've read on their website, only encrypted 
push notifications need a subscription, which is not necessary for talking 
about Free Software anyway, if we're being honest.
None of our current Telegram or IRC communication is encrypted, so why would 
we need encryption for Mattermost?
I cannot see anywhere that the Android app only works at all with a 
subscription.
