I don't think 'out of the public eye' is really a requirement for something to count as counterculture. 60s counterculture was highly visibly, a zillion people showed up to Woodstock, etc. 'Successful' counterculture eventually bleeds into and is sometimes outright absorbed into mainstream culture but that doesn't really make it not-counterculture the moment it gains visibility.
