It's Latin so it must be smart.
Apparently Twitter had some huge problem with bots when Musk was trying to get out of the purchase. Thankfully he solved the bot problem after the purchase so he could run polls and really get the will of the people and not, you know, all those previously problematic bots.
It's perfect, in a way, that the full quote is "Nec audiendi qui solent dicere, Vox populi, vox Dei, quum tumultuositas vulgi semper insaniae proxima sit." which translates to "And those people should not be listened to who keep saying the voice of the people is the voice of God, since the riotousness of the crowd is always very close to madness."
