What a ridiculous over reaction. * this is still open source. Fully open source. * this is currently only available on MacOS All that looks to have happened is the developers of this single feature that is in the nightly build are using Macs. It is wholly reasonable for them to only support one platform at this point. If it is a good feature they, or other devs attracted by this preview will port it.
