They also have other weird things going on. Like GitHub actions which are billed by the "minute". Just that windows minutes are two GitHub minutes and macOS minutes are 10 GitHub minutes. And there I thought minutes were 60 seconds (an SI unit)...
Why not being honest and call it credits?
Not to say that a few months after introducing GitHub actions the few "minutes" got reduced from 10k to 2k.
Next step would be showing price in $, but not USD.
