Yeah, call me slow but I finally get it.
The study wt associates the internet with porn as a scare tactic. Even then they won't be up-front and suggest doing without, but indicate it with that sleazy assertion that "some" choose not to have the internet at home.
The context suggests that those who do are weak in faith and very likely surfing porn. So a believer must now be suspicious if a partner or teenager insists in having internet available. A lot of family arguments and angst follow, courtesy of the wt.
HOW DARE THEY manipulate people this way???
