Con No command line solution
Con The developer sucks
You cannot get real support, it's everything 90's style there, a forum that created since 1990 and nothing interesting, also when you request something it gets deleted by the developer or you got ban because the developer doesn't agree with your opinion.
Con Vague information on validity of purchased licenses
Developer only says a license is valid for "several years" and is known to have intentionally voided licenses that were specifically described as lifetime licenses for repeat business.
Con Old bones
It doesn't help when a program has old bones.
Con Developer is acting like Hitler uppon feedbacks and replies

Con No official GUI option
While there are some unofficial remote graphical interfaces available for WeeChat, it is intended to be used as a terminal client. As such it might be challenging to use to those accustomed to graphical interfaces.
Con Scripting API allows poorly written scripts to be used as attack vectors
Plugin documentation includes the following warning:
In many functions, for speed reasons, WeeChat does not check if your pointer is correct or not. It’s your job to check you’re giving a valid pointer, otherwise you may see a nice crash report ;)
