It's not a full replacement, but it's enough to keep people content with the status quo.
Traditional ways of meeting a spouse don’t involve slutty costumes at once-a-year parties (Halloween is not a spouse-selection fertility festival), but family, church, and neighborhood connections that build over spans of time in 3d. Sometimes HN seems to miss slow, complex, physical-world interactions because of a focus on modeling transaction-like events or instants (like parties).
The people who were in college in the 1980s aren't millennials. If you were 22 in 1983 then you were born in 1961. That's not even Gen X, that's a boomer.
And Halloween in particular isn't really the point anyway. The decade associated with topless hippies and free love was before the 1980s. The Romans would dispute the notion that this sort of thing is a recent development.

The thing about imposing content restrictions via corporate intermediaries is that they're not that selective. If you're not banning cleavage and innuendo from the mass market services then they become the funnel to OnlyFans and escort services, but if you are then the result is a de facto ban on real people flirting with each other because they're afraid of having their account locked.
Consider what "chilling effects" implies in the context of sexual expressiveness.
