What's Going on With Zero Royalty Exchanges?

The median royalty portrayed on OpenSea this summer was around 7% versus 4% last year. I'm curious, do you think that average royalty portrayed of 7% is a function of collectors feeling like they want to give back to the projects and support them through royalties or a feeling of the price and sensitivity that exists at the royalty level when they're thinking in terms of the three X or the four X?
