You're right. But I'd assume anyone using Linux (and arch at that) would be smart enough to know what's up. No OS is perfect but someone using Arch is just spreading FUD. Windows is a vector not because of security problems but because of its usage ratio. It just doesn't make economic sense to target any other OS plus the fact that hackers are not god, they need time to perfect their skills and they have it on Windows. Denouncing an OS despite the fact that it has stellar security on its own is basically bringing down people like you and I who are spending days and nights making things work for fine. Denouncing for valid reasons is fine. Security in Windows is not Microsoft's problem. They're trying their best, they're not all knowing. That loser on Arch should talk when Linux and macOS are completely impenetrable.
