Probably like so many others - all depends on where it happens, the general access to the location, and the attitude of those attending.
I believe they have been to Oregon twice? For certain once in the last decade - much controversy leading up to it. I do not believe it can be said they were 'no trace' by any means and it was a disgrace by somes definition when they left. The crowd was not as big as touted, there was damage [significant depending on what narrative you wanted to push], and the majority were willing to leave it in bad condition - that said, many stayed behind and worked to clean up the site.
I do agree the level of hipocracy seemed high at the time but that is par for the course these days - IMO. Whenever a significant number or people gathers in one area, you won't want them and you won't want them back.
