I don’t disagree on your view of MS and google but I do on the politics.
Even huge corporations need to abide by the law (or pay fines) e.g. usb-c charging. We can do it, we just need to stay on topic. Discussing why google and ms (and others) wont do it is only going to hurt the idea because people love to hear „but we can’t change it anyway so you don’t have to do anything“. Instead we forget what naysayers there definitely will be and just push for it.
