I really don't think that the vast majority care its just other DJ's and collectors that are bothered. You generally check a record on the deck if it is a rare track and you are ogling at the label. Bit like looking at a Sports Car that is parked next to your Car in the Car Park. Looks gorgeous, couldn't possibly afford one so I'll carry on driving around in my 1995 Polo !!
I think we should have the common decency to let people know that the venue is an OVO venue and it is down to the Promoter to 'uphold the Law'. If they are found wanting then they should be brought to trial and explain the infringment.
It generally all boils down to honesty and integrity. Collectors and DJ's who do, collect OVO only. People who don't tend not to understand why those that do, do ! It isn't snobery or elitism, its down to personal preference.
I collect David Bowie items and have a miriad of items, all Original release. Don't get them to play for anyone else or even parade around my friends, it's just for personal gratification. Just so happens that on there are venues that allow you to play your old Soul records, not so many for the Bowie stuff !!
I think 'The Scene' is dead for some people Bazza but for others its still alive and kicking. It's just not the way we remember or would like it to be.
