This is one of the posts where I just can't go away without commenting. I will be always on the side of the open-source developer basically in any situation. BUT (of course there is "but") in the post about selling plugin (Why I'm Charging What I'm Charging) author stated that he is made decision based on the fact that he bought Mac for developing Apple Silicon support. I will not pretend that I read everything in both posts and even fully understand cross-platform part in the project BUT as Apple hater I will say that author could just drop Mac support as alternative. Again I don't know if author's project can run on Windows ARM and if he ever bought Project Volterra. So if Mac made you paywall your plugin than sell it to Mac users and leave Win\Linux open source.
