I think it's a brilliant move from the people behind Telegram: all cryptographers will now keep the vulnerabilities they find to themselves until March 1st. This saves them from a lot of bad press now, and probably doesn't cost them anything.

If they were serious about using their $200k for their security they should have either: a) Hired an actual independent cryptographer to do an audit. b) Set up a bug bounty program that rewards any weakness found, not just this "all-or-nothing" contest they have now.
