I usually hate it when someone uses this argument, but like a good hypocrite, here I go.
Moffat and RTD are not making this show for its fans. They're making it for its audience. And since most of the audience probably don't know about the regeneration limit, they don't seem to feel a need to include it. In the end, it's the audience which provides the ratings, not the fans. If it were for the fans, than I'm sure the Doctor and Sarah-Jane and Jo Grant could sit down have a lengthy discussion about it and other fanwanky things. While this would please the fans, the audience would not enjoy it and it would not bring in ratings.
My issue about them doing away with the limit in this episode is why is it even being brought up in this particular episode? Whether Jo even knows about regeneration is contingent on if she remembers the events of The Three Doctors. And while Sarah-Jane obviously is aware of regeneration, she wouldn't know there's a limit since it wasn't established until after she left Doctor Who.
