Incorrect,
there is some free shit. Not much though. As for why content isn't readily available unless you subscribe; Fakku no is no longer a pirating site and hasn't been for give-or-take about three years now. It's a full-fledged business which publishes uncensored and translated chapters from normally Japanese-exclusive magazines. The fact that you notice
now suggests to me that you didn't care all that much about the website to begin with, until you noticed it no longer provided free content.
HentaiHaven hasn't had consistent uploads for quite some time and has long-since become redundant in the wake of sites that publish more frequently and with better layouts. However it's a home-brand for pretty much anyone who's been into hentai for some time, and Fakku have been wanting to publish H-anime. Snapping up the HH brand is a convenient solution.
