Think about things that are outright criminal, that breach the TOS on most websites, or that are wildly offensive or ridiculous. Being repulsive doesn't mean something isn't a counterculture; in fact, it can be sign that it is.
Illegal shows? Well dead city punx just had an illegal show in the LA river! Cops couldn’t even break it up. Streamed live on IG, lots of good advertising content.
All counterculture is mainstream, all of it is profitable with advertising. Burn a house down, riot about capitalism, at the end of the day you’re making a capitalist or mega corp money if someone can get the content from a device.
Want to truly be rebellious? Be boring and stop using social media.
This is today's counter-culture. Something like the final scene in 'Fahrenheit 451'.
Maybe in America
