But should they be?

Say there's a Toro site for add-ins (flashing lights or whatever, I have no idea how you'd mod a mower...lol).

And some of those add-ins will void your mower, and potentially break your machine. It's certainly within their prerogative to say "We won't host them. But you can just go to <some website> and get it from them instead". In fact, doesn't Google make a search engine? Surely, it's not hard to just Google for Cyanogenmod and find their hompage? In fact, if you can't do that, then probably shouldn't be flashing a ROM...
