This is only true if you're using exclusively Linux runners. If those same 7,000 minutes are on macOS, you're paying $560. On Windows, $112. At my company, we definitely use a mixture of all three for various things, so this will sting, with varying degrees, depending on how often we build new iOS, Mac, and Windows releases.

Builds on macOS and Windows already depleted your minutes credit with a multiplier (Windows 2x, macOS 10x), so this shouldn't change anything
