This continues to be silly. There were changes to Crew 9, last summer, when it was decided that it would be logistically easier for two (instead of four) astronauts to go up and the two Boeing crew would come down with them on the Crew 9 craft in February/March 2025 (that would be now). This has always been the plan, the only politics being injected here are people insisting on grandstanding and making drama where there is none.
You can disagree with the decision (though, again, why), but it was a decision. There was no dereliction of duty, no stranding of astronauts since September, and this was not some high-stakes rescue.
It's a simple, parsimonious explanation for everything that has happened since. Nonetheless, we apparently have to talk about it.
I wonder how many people expressing strong opinions don't even understand that there were intentionally empty seats.
It also led to some interesting improvisations. NASA has a requirement that there be a 'lifeboat' on the ISS for all crew in case of an emergency, but because of the Boeing crew (and the lack of a corresponding vessel), NASA approved a new 'configuration' of the Dragon where up to 3 people could strap themselves to the floor of it, where cargo would normally go, in case of the need of a mass escape from the ISS.

As another fun aside, when the Starliner was returning [autonomously] to Earth it experienced two more errors, unrelated to the ones that left the astronauts stranded on the ISS in the first place. What a vessel.
