so it cost anthropic $20k to find this openbsd crash bug which amounts to putting a negative integer in a tcp field where a negative integer was not expected by the c code which does some cavalier int cast bullshit, ie. a vuln which is totally fuzzable, and quite certainly would have been found by the fuzzers of the 2010s had anyone cared to burn that much compute on fuzzing openbsd.

The difference today is not that anybody suddenly cares about investing that much in openbsd (is the build server still a donated machine running in Theo's basement?), but that openbsd's reputation for security makes it really good marketing if you can find a bug, any bug, it doesn't matter; and that marketing value is what makes it worth spending $20k on fuzzing.
