PR scheme. Just like I said in my OP.
But why? Blackpink already made headlines everywhere with their comeback, Spotify records, Youtube records, Kcharts, album sales, top 10 in US Spotify and potential top 25 in Hot 100 if the song gets radio support, and soon they'll have VMAs then the actual album. Plus Jennie's debut in the HBO drama. This all happened before the pics leaked.
These PR stunts are for celebrities that are fading. If anything BP is still growing.
