Actually 802.11b DSSS does meet the definiation. It was when 802.11g OFDM came out they had to rewrite the part 15 rules as it wasn't considered spread spectrum. And ATV, which what it appears the WISP's are most afraid of, was never constrained by the APC rules.

True, but I'm reluctant to argue this point. One of the basis and purpose of amateur radio is experimentation, and to promote this we need as few rules as possible. It also is informative to look back at why APC was implemented... it was to protect the vested VHF/UHF weak signal DX'ers (look at the reply comments). The "threat" of spread spectrum never materialized so the ARRL wants to discontinue an unneeded rule.
