Okay, lets see reality:
Curtis lies and tries to paint himself the good guy and everybody who doesn't bow to him is evil
Hooray labels user as "leeches"
Bugman uses a never decided on manifesto to make people believe there is some officila paper and uses politically motivated banning
Stuart as the fist of his masters is a willing tool of his masters
Thorsten runs wild, gets caught lied, has others ban everyone who calls him out for lying and starts again
FGmembers as an organization has cultivated an atmosphere of anger and disdain towards a list of specific flightgear contributors and towards this forum. And in return, their representatives (whether in an official capacity or self-appointed) have exported nothing but chaos and arguments back here to this forum.
So, lets see, actually your little bunch of hitter has created an atmosphere of political oppression, a culture of those who are allowed to ride any attack and those who have to duck before the shadow of the great leader. And you defend this culture with lies and propaganda tricks, and so do you little helpers. The mechanism is easy to spot, we have seen it in much bigger scale dozens of time over history. You let your clowns even run Stalin style purges on the forum and clean the Wiki in an attempt, people don't hear about FGMEMBERS. Your little propaganda secretary was even thinking aloud to pull the plug on MP because people hear and see too much there. Like every dictator, you have tried to created a bubble in which members of your forum wouldn't get any information that could disturb your and your helpers claims on power. You only never realized, you can't do what Kim does in NKorea, the Internet is a free world, GPL is a free world and thus opposite to Kim, who denies his people Internet, people will hear about it, they do all the time.
Now, here is the rub: We had in the last weeks updates on A310s, A340s, a 777, a BM-2 and more, just in the last two weeks, they are all GPL, you can take them. Now, can you commit, you will take them. Can you publicly state, we can put them into FGADDON? Can you guarantee, they will not be rejected if we send them there? Can you guarantee, those updates are available to the users, the leeches as Hooray calls them? I bet you can't!
The problem you have is, that almost each and every content here was attacked too often by Mr. T to have any trust into FGADDON and the people who run it. Some are banned, some were temporarily banned, all were targets of vicious attacks by your dogs and got their posts deleted over there. Add to this the users (those people who do a lot testing and feed us all the time with new ideas). You seem to think, we are just three people and one of them is not even a content dev. Actually, the number of people, you and your kill squad have pissed off has reached approximately the size of the active core of your own forum. And don't forget, there is an overlap because opposite to your politics, we have here no exclusivity policy.
I can't count the content commits, maybe Israel finds a clever way, they are just too many. Scenery, aircraft, there are on some days easily a hundred commits, if not more. As you said, this exists for almost two years (so your and your attack dog's screaming "don't go there, it will not live longer than three months" is already proven strong) and it still grows.
Now, nobody here has ever told any content dev not to send stuff to FGADDON. Actually Israel encourages to send to both repositories, but many here don't bother anymore to send something to your gatekeepers. I mean, why? You sit there put hours on end in an aircraft, then you have to do the kotau, kiss the feet of people who think, from their rear shines the sun and then, you get a rejection note anyway because you said something "politically incorrect" in the past. Or you press push, make a pull request, any your work is out there with the users, you can go meet with friends, start qa flock of those birds and have a good time. Or go for the next plane, whatever floats your boat. No feet kissing, no bowing to a wannabe-emperor, no rejection notes for political reasons. So you can see why Israel, who enjoys a lot more sympathy and respect here, than you do, can encourage people also to send stuff to FGADDON but fails, because FGADDON is a political mess. So why on Earth would someone who wants nothing but make an aircraft or an airport go there? Why?
