Sorry I used the wrong phrase its their tos. tldr despite being built on open tech (hole punch) they will sue you if you reverse engineer it and try to figure out how it works. They say they dont collect data but with a "balck box" we dont know for sure and I could be misremembering but I thought they talked about open sourcing keet. So I wanted to wait to use it until then but after reading the tos I doubted that it was likely and decided to stay away from it.
