This is literally the foundation story of numerous billion-dollar businesses. In fact OpenAI managed to beg their way into a trillion dollars after losing money offering no kind of product for many years. It sounds like it's just a business plan that you don't like very much.
Off the top of my head, I believe Twitter, Youtube, Discord, Reddit, Imgur each had no monetization at all for the first 3~5 years of their existence. Or more recently there was uv, that write-it-in-Rust Python package manager that had no avenue for monetization but received millions in investment funding a team working on it full-time until successfully getting bought out by OpenAI.
