A lot of people rate Facebook at 1-star because they don't like Facebook as a whole (I think I saw the term "protest vote" somewhere else in this thread). The reviews that just say "I hate Facebook" clearly aren't indicative of Home as a whole.
So either there are some dedicated facebook haters out there, or the people who tried this app really hate it that much...
I read this a while back on a HN thread and it resonates more and more by the day -- there are a number of dedicated haters such that such things don't suprise me...it may need a bit rough on the edges but some take it a bit extreme
Seems like misdirected outrage...
They really showed them. https://www.youtube.com/watch?v=NUHk2RSMCS8
