Why is it that TV and Computers are consider hazardous waste
because of the lead in the glass? Is that going to magically leech
out of the glass?

AFIK, it ISN'T the lead in the glass, its the phosphors, and the lead

The lead does leach out of the glass in an acid environment. Acid rain
is plenty acidic enough.
