Why do people hate on Dropshipping in 2026

So I build my website and made a businessplan based on dropshipping, (Reselling without having stock) and I dont understand why it is so hated. So I am Selling calisthenics equipment. But because I want to start small without loosing monney. I am dropshipping them. What is wrong about it. Isn´t it just the same as Having my own stock, just that my stock. Please clear me up why people say there is no chance of making money with dropshipping in 2026. And no Im not tryna make it myself easy. I just dont want to start with a own stock.
