That's not abuse.

If the developers choose to support that hardware, they have a reason. In either case, there is no way to use open source software that's abusive, with the exception of stuff like Amazon taking an open source project, modifying it without distribution so they're not obligated to share their changes, and selling the product as a service (at a scale that makes it extremely difficult for the authors to compete). That's against the spirit of open source even if it wasn't foreseen when licenses were written and is hard to legislate.

Using open source software to save money isn't.
