I love how they mention X (Twitter):
> We are a separate company from X Corp, but will work closely with X (Twitter),
> We are a separate company from X Corp, but will work closely with X (Twitter),
I see no clarity issues here.
E.g. 1, 2 and 3.
Or for further clarity, each entity could in fact be denoted by a key feature, e.g. Messenger, AI Shop, etc.
Any particularly memorable phrase may do well to differentiate the specific entity from others in the market. All kinds of analogies can be used here creatively!
