It is absolutely unfair that anyone should have to learn anything about web hosting and payment processing to sell things online.
It's absolutely ableist that etsy (or whichever other free and easy platform) can't be trusted.
It is absolutely cruel that the modern web is designed to extract as much as it can from you, and to give as little back as possible -- to make you dependent on their services, and then to make those services worse and worse at your expense.
