They had the option to return at any moment in case of emergency. They were never “stuck”, that’s just something the media made up. Emergency evacuation of the ISS is possible at all times, that’s a pretty strict rule. They just chose not to, since there wasn’t any real reason to. Sure it was unplanned they would stay that long, but those are still two very valuable crew members that can do a lot of work. So they just did their job. And as both of them worked very hard to get there, staying wasn’t really a punishment or anything.
In the end they went home on a different vehicle, as the one they arrived on had too many issues to risk it (even though it worked fine in the end, but they didn’t want to take unnecessary chances)
