Hello Jedgar,
Same as Dave said. I consider our relationship as a collaboration where I transform LiveATC audio into videos which contain radar animations, transcripts for people who find the audio difficult to understand, and more. The purpose is to give the audios a visual content for the viewer to visualize what is happening.
If you enjoy the LiveATC website, they of course would appreciate your donation - no matter whether you watch VAS or not because you're not paying VAS for anything. You have hundreds of audio feeds here to listen to ATC all over the world which need support and maintenance so any donation to LiveATC is helpful for the goods of the entire community.
Safe flights!
Victor
