Outside for same reasons that a POTS (conventional telephone) NID, AC electric meter, gas meter and shutoff, etc are also outside. For example, service performed without anyone being home.
Electrical clay is perfectly good moisture protection. Normally, electrical clay is black. Clay is rarely applied 'pretty'. A better clay seal is a lump to make a moisture resistant barrier.
Of course, better installations also use a drip loop before entering a box or building.
