I know that's probably a joke, but that would be incredible bad for NASA. There is already strong competition for access to docking ports on the ISS. Losing one would badly complicated logistics on the station.
On the other hand, if the leaks are at the manifold then starliner might become an ISS module indeed, but taking up an airlock is bad news nonetheless so they would still have to find a way to jettison it.
Every single person at Boeing should be full of shame at this entire process. The thing is an utter joke to everyone.
If Crew Dragon needs to be launched to bring back the Starliner's passengers, that should be the final nail in Starliner's coffin.
I'm seriously shocked that NASA allowed themselves to be bullied by Boeing to allow this thing to have been launched at all.
I'm gonna go with Hanlon's razor here. The Starliner team seems to have enough trouble just getting a single Starliner to the ISS without issues, I can't imagine they're capable of devising a malicious plan to interfere with a competitor.
