I am not qualified to make any comments on the legal difference between the terms either, and I should also add that I am an ESL, so take that with a grain of salt.

Reading the original comments about being "liable", it felt like another way of saying "there are consequences to your decisions, and as the author you bear some responsibility of what you put out there", which imo is pretty far from how the author of this blog post described it, hence me calling "a pretty big stretch"
