I agree, and celebrate the choice, but if you feel more strongly about the oppression imposed by customs, it may feel something like seeing a battered wife returning to her aggressor (except the "aggressor" is society, not the husband).
That said, even if you think the person made a poor choice, criticism and cutting off relations is a terrible response - in either case!
I think it's hard to disparage when any partner chooses to stay home -- and isn't choice a core tenant of feminism?
