Some are weebs that are too deep in the rabbithole that simply would prefer the loli to real CP despite their pedo tendencies because they don't like flesh bodies visually.
Personally I would assume he doesn't have real CP (which isn't hard to track down for the cops) but has lots of loli encrypted since it has social consequences anyways.
And like other nona says it is seen as a libertarian/ancap symbol against government censorship and surveillance (not justifying them).
Anyways he's not your problem anymore, don't talk to him and change your passwords.
