While true, this doesn't address the fundamental complaint that the
licensing of the OpenSSL compatibility layer renders it worthless for
most applications.  The ironic result is that those who write
GPL-compatible software are free to use the older APIs that are
historically associated with GPL-incompatible code; and those who write
GPL-incompatible software, free or not, must choose between using
libraries that are wholly GPL-incompatible, or using libraries with a
learning curve.

And Debian is stuck in the middle.

Sure, code can be rewritten to use gnutls natively.  But I don't
understand why anyone would consider this a useful expenditure of
developer resources when the necessary OpenSSL compat glue could simply
be made available under the LGPL.
