I see absolutely no relevance to whether tickets are sold, whether it is on public property or any of the issues such as standing or singing. In some people's mind the flag, national anthem, etc. are "special" as targets for protest; but really, they are not. What has been decided is these are not "special" items of protection against such protests.
