When writing ChatSecure I followed the logic in this post on StackOverflow:

Since I distribute the object files in question with the app (and my app is
open source) I feel that I don't violate the spirit of the LGPL. However,
I'm not a lawyer, and I know that some FSF devotees would disagree with me.

I have been considered reimplementing libotr in Objective-C and licensing
it under BSD as well, but I wanted to wait until after libotr4 / OTRv3 was
released. I have had some interest from another developer looking to fund a
rewrite of libotr to use the iOS Common Crypto routines. Maybe we could all
work together.
