Needing to use "The Le Epic prefix" is absolutely not necessary because it's too much investment into regularly acknowledging and sharing an opinion on the dumb idea when you can just call it twitter like most people still do and be done with it. If you need to think of that as resistance, you still can! The guy really seems like the type to be more peeved about people ignoring his ideas than denouncing them.

You don't need to respond to an instance of someone referring to the platform as "x" with a statement on how you feel about it, you can just call it twitter when you yourself talk about it. Whether it's because you actually don't care or because you want to be the change and all that, either way it will make your life a little easier.
