LocalSend. It’s exactly like Apple Airdrop

This may be super-nitpicky (and I lose LocalSend and use it a lot), but there is one difference between LocalSend and Airdrop. LocalSend requires network connectivity (and requires the devices to be on the same network), whereas Airdrop can work without any network connection (using Bluetooth).

Linux is the only platform to get native WebGL, too!

It doesn’t change the larger point that GNU is way bigger than Linux, though. There are a tonne of things that are larger than Linux, and GNU is one of them.
