I love them! Free users are still validation that there is a demand for what you’re building. Ofc it might still be the case that most people aren’t willing to pay for your product, but you’re only going to find that out once you keep building.

This is exactly my approach with https://rockyai.me/ - chrome extension that lets you chat with any webpage using LLMs. I have zero paid users but a lot of my friends love the product so that’s still very satisfying!
