why be open source? so someone can take the code, make a crap version, and confuse people.
...which is not the point of open source though. BitTorrent itself is open-source, and look how it is florishing. Many open source projects I know are just flooded with commits, fixing bugs here, boosting the performance there. And, oh wow, they still work and people do not get confused!
On the other hand, if the author of fopnu and Tixati disappears (which we do not hope for the next decades!), both programs will be obsolete after their last update. What then? Abandon Tixati/fopnu? I doubt many people would prefer switching to another client of their taste (which is hard for fopnu and its own, special file transfer protocol, as it is the only program to support it), but for BitTorrent and its ongoing development, it can be the only thing for users of Tixati to come (unless they want to use the outdated version in the future).
So with the demise of fopnu, there is the demise of fopnu's protocol. Surely people will use it furthermore, but using outdated clients and protocols is risky, as malware can be spread super-easy and malicious codes could be executed without the user knowing.
Now, quite a few users of Tixati do appreciate the program becoming open-source, as some "features" in it make them unable to work with Tixati in a useful way. I love Tixati, but e.g. the feature of faking its peer-ID makes me not want to use this program any further, as some trackers wouldn't allow Tixati although everything that is needed is just working fine (e.g. sending the correct data back to the tracker - which was the main issue of Tixati being banned on many trackers).
I know, I know, sounds horrible - I believe that Kevin will pass on the source code to someone else, someone loyal, to let updates be rolled out for the coming years/decades.
Respecting the authors of fopnu and Tixati, I do understand them in some ways. It is your own little project, that you treated with love and worked on with a lot of time. With open-source, there don't always come many advantages, but, excuse my tone, idiots, that think they might be smarter than one on their own. Creating codes that make the program worse, "fixing" "bugs", and all that stuff combined.
If you ever read this, Tixati and fopnu guys:
I really, really love your projects. But please, keep an eye out for the community. Even though there are a lot of people writing nonsense, there indeed are quite a few giving good advice. They probably even donated once, which I would do, but some things, as I wrote, hinder me from using fopnu and Tixati.
Other than that, I congratulate you for reading this wall of text.
