I personally find downvotes useful because there are a lot of low quality comments and content. Downvotes help me (and others) to avoid seeing them. Thus not wasting time with uninteresting posts or comments. But you aren't supposed to downvote everything that someone says.

By the way, I think it's very cool that you're writing your own engine. UE, Unity and even Godot are quite bloated.
