Oh right, I keep forgetting that. The LGPL part is just the library that lets apps talk to the driver. I still think the main thing Interception has going for it is code signing. I once wrote a keyboard filter driver for personal use, but due to signing requirements I never felt it was worth the trouble & cost trying to use it past the computer I developed it on (and then later moved to firmware based solutions like QMK).
