I think there's some talking past each other going on. I don't think anyone is saying "no, we're not going to be friends first, we're going straight to lovers!". Of course you talk initially, get to know each other, find out if you like each other and see if theres a connection that can develop over time, wether that time be weeks or months.
I didn't spend hours creating a detailed and intricate profile trying to explain who I am, what I want and who I'd like with me when I do so the site algorithm can present me with some quality potential matches, a few of which might pass a detailed inspection and warrant contacting just so I could send them "sup bb, u want sum f*k?"
By signing up to a dating site, you're putting the cards on the table. You're saying, "yes, I'd like to find a date". By putting emphasis on the "friends first"* thing, you're effectively saying "I'd like my cards to remain hidden.".
*which, in my experience, is much more common in profiles that are short on personal info, but heavy on pictures.
