since the founder of Twitter (jack) focused on developing the lighting network, I suspect he will never make a new token that will be the opposite of bitcoin but Facebook has long announced they will issue their token (which is still not circulating). offend google. It seems that there will never be tokens issued by Google, because for what else are they issuing own token, they have become a big platform.

We dont know about Diem or coin attached to it since its really still not be seen in terms of circulation or something.
We dont see for Twitter to be that interested on making their own but instead might have possibilities on integrating existing coins in the market.
