I know it's just a name, but what's wrong with calling it what it was already named? A name that everyone knows it by, which is aso a name that rolls nicely off the tongue: Transbay Terminal.
Salesforce transit center? It's one thing to name a tower after the company that leases the most space in it...but a public transit station and park?
Is embarcadero station eventually going to be named Twitter station, after they agree to pay for an art installation or something? Union Square will become Facebook Square? Or maybe City Hall will become Airbnb Hall, after they pay for a new lighting system. Etc, etc...
At least when they did it to SF General it was person's name instead of a company name.
