WebRTC really is next level when it comes to video communication. I've tried Proficonf, and it's awesome. Its quality is direct proof that WebRTC has no alternatives when you want quality.
While temiri is right, I'd like to continue the discussion that you've started by mentioning that their last airdrop, done in collaboration with blockchain.com, was also a fiasco. A lot of people didn't even bother claiming anymore, and many of those who tried (including me and a buddy that lives in the same building), weren't able to claim because the process was littered with bugs. Hopefully, a serious non-profit foundation will take over (fork) the open source Stellar tech, create a good and fair initial distribution mechanism, and then restart the cryptocurrency. It would probably need the help of governments or big corporations like Facebook/Google in order to insure a fair initial distribution.
