It's another cause of some very rich person that does not think they have to follow the rules.
It's like a very successful restaurant next door to you deciding to expand with an outdoor patio that includes a band. All the home owners next to the restaurant disapprove of the plans but are brushed off. The very successful restaurant owner has the money and connections to push for the approval. If they get the approval it is the home owners that have to adjust to the noise with noise abatement improvements while the restaurant makes more money at the homeowners expense.
