So paid commercial apps like Better Touch Tool that implement snapping are also infringing? MS developed MTP but at this point it's a part of the USB standard.

So paid commercial apps like Better Touch Tool that implement snapping are also infringing? MS developed MTP but at this point it's a part of the USB standard. Many Android devices lack exFAT support but do support MTP which suggests to me it's not patent encumbered. Google has an app for Mac OS too, so no it's not just OSS once again. It's more like Apple deliberately knee-capping non-iPhones to steer users towards iPhones. Windows 11 includes a package manager, winget.
