In my experience the SaaS unlimited abusers often aren’t even trying to do capitalism things. They’re just abusing the systems for the thrill of it.
They go on Reddit and brag and compete about doing useless things to store files on these services, like a competition. They’re bragging on HN about GitHub tools that force files into a non-file service and have rate limiters tuned to upload right at the server’s rate limit.
It’s not capitalism, it’s people thinking they’re winning points against capitalism by abusing a corporation. Even if that corporation is a small startup trying to offer a product on a small budget.
