The whole situation reminds me of the opposite of BaseCamp. They got rid of all tiers and went unlimited to simplify the product. And they still rake in the dough. You fundamentally make your business more complex and costly with all this non-sense. The difference is BaseCamp doesn't have VC influence. So the cult of growth and squeezing people for every penny isn't in their DNA.
I think the VC and Silicon Valley influence on Patreon may kill it.
