Someone always has to ruin it for everyone else.
I was thinking more along the lines of showing people how to do it, not doing the work for them. They might as well learn from the beginning that gardening is not a spectator sport.
But, if you wanted to stay with doing it for them, have firm limits on the size of the new pot and number of plants for it. Nip that abuse crap in the bud, so to speak.
