True.The point is BRS is not the only place to buy stuff for reefing, and not the "one ring".
I think he means that Bulk Reef Supply has or might get the ability to stop others from selling and become the only place you can get anything they control. If they bought out a couple other companies, they could pretty much control the entire hobby.
Like Ecotech owns AI, but Bulk Reef Supply owns Ecotech. That means Bulk Reef Supply has the ability to decide to be the only place to get the AI brand. Customer service would be the same way.
