I don't think you replied to my suggestion of not changing the development and release process at all other than releasing a source archive with every binary release you make?
Because that wouldn't stop the usual noise, would create the trolling that is so much the nature of this "community", and it would still create forked system components, creating an overall setup that is not maintainable anymore. We already have this trouble today, now multiply this by the number of Os components and the number of custom builds. It is already hard enough to debug a system like AmigaOs as "patched up" systems are the norm and not the exception. If we now add "patched up system components" to the game, how is that going to help?
Whoever wants to develop is invited to join, but with coordination and moderation, please.
Needs zero additional governance, and no project or community management skills that aren't already required anyway.
Huh? But of course it needs "additional governance".
Yet, it guarantees we're not facing the next dead-end if Thomas leaves the Amiga scene for another 15 year sabbatical or Hyperion turns out to be not as stellar an outfit as we all assumed (or simply vanishes).
You already have the dead-end. Access to Os4 would be finally lost, and I'm personally not willing to develop in the kind of aggressive environment that is the consequence, well knowing the "community". Thanks, but no, thanks.
Are you saying Thomas is not professional enough to prevent fragmentation? That's mean. Or, to use his words: "stop trolling, you have no clue" 
No, I'm not. How ccould I prevent that, with the sources out of the door? That is impossible. Besides, why should the work break down without me, on the Hyperion side?
Or, for the sake of the argument, let's consider Cloanto makes the Os open source. Who prevents me from taking the sources and create my own fork? I can develop indepedently, publish what I like, and avoid communications with Cloanto. They can do what they want, I can do what I want, then we have AmigaOs times two. As long as I can use mine, I'm happy, and Cloanto, well, that's their problem then.
We established that fragmentation has become pretty bad already. We also established that the source code is already easily available and that people are doing things with it. We also established that people don't care much about copyright anymore - that includes the 3.1.4 team, which works for a man Thomas himself accused of pirating 1.3.
I'm sorry, but I care about copyright. If you say "people are doing things with it", well, then that's "a fork". I cannot prevent that, but at least, the current situation we have now keeps the damage somewhat under control as such copies are not floating around, and it also prevents users from filing reports.
Yet, despite all of this, 3.1.4 was quite a success. I don't see any evidence things might get worse on the fragmentation front.
I do. Look around,
Can you name any coder who could pull of a AmigaOS/Kickstart fork and isn't (a) long gone, (b) busy with AROS/MorphOS/OS4/ExecNG (c) stupid enough try to compete with a competent, well-respected team that's been working on the code for years (d) disillusioned by the prospect of being ignored due to not having THE NAME (e) laughed out of town every time he suggests he could improve some library? I can't.
Yes. Me. (-: Let's consider: Again, for the sake of the argument, why should I be stupid enough to work for Cloanto for nothing if I can work for myself for nothing? (-;
Or even differently - I do not get the "business model" Cloanto has here. I don't believe that they are that folly.
