I interviewed with one of them, and they picked a fight with me about advertising because I felt my previous employer had taken the absolute lowest possible road. I continually tried to acquiesce, even noting that they had a paid option, and they basically said that they hate their paid customers, who they lose money on (why not charge us more?!?), and that they only ever did a paid option because they were forced to.
Pretty sure I had been using their fucking service longer than anyone I interviewed with there, but whatever. ;)
