It's crazy naive to not see the implications of this
This is a President who wouldn't even use the designated @potus account because he is so narcissistic he wanted the follower count for himself.
You might argue that it has lesser reach compared to a major social media site, but there are countless individuals and organizations that would jump to be the first one posting a link to a presidential address on social media sites.
Which is more than just semantics. Suspending an account and the associated momentum without actually banning the person might be a good mechanism to have in place.
Regardless, if Trump wants to, he has official means (through whitehouse.gov) to issue statements. He choose Twitter when he had other options.
