Well hopefully spending less on legal is incentive enough. Knowing their ToS is enforceable is also a boon, unless they are deliberately trying to make the ToS in the grey, but then they probably wouldn't want to use a standard ToS anyway. If if were to catch on hopefully user and social pressure would help to keep its adoption up.
