    1010kzblocked wrote a Windows program that allows obfs4 connections to succeed, by shrinking the server's TCP window so the client's first packet is smaller. Like [https://github.com/NullHypothesis/brdgrd brdgrd] but on the client side. They seem to think that only the first segment is being looked at.
    11  * A first segment of 1 byte doesn't work.
     11 * A first segment of 1­–15 bytes doesn't work.
    1212 * A first segment of 16 bytes works.
    1313 * A first segment of 16 bytes works also for unobfuscated Tor TLS.
