But the paragraph quoted above came from Google’s TOS for the new browser beta Google Chrome. All it took for Google to listen and change the TOS was an article in slashdot. Almost overnight, Google changed its TOS and posted an explanation on the Google blog: Google does not want rights to things you do using Chrome.
As for Lijit, we heard from them during the discussion here about their TOS, but if that has changed since then, we haven’t heard about it.
