This whole 'banish CUSA' thing is silly. Even the idea of 'banish CUSA off the front page' is silly. If CUSA is not 'Amiga' enough, then neither it s OS4. The original Commodore didn't make it, and never made anything for the PPC. So, MorphOS is out too. The MiniMig is certainly not a 68000, and RetroReplay isn't a real Amiga. Nor is Natami. We can banish Amithalon as no different than CUSA, since it was just Linux on an x86 with emulation and some integration. And we can't forget to banish UAE. We could give AROS a pass, but only for the 68000 as that is the only version that runs on an actual Amiga.
By the time you banish everything that wasn't produced by or for the one true commodore, you have very little left.
Amiga.org is in the unfortunate situation that it has a few members who go out of their way to troll the board and insult other members. The moderators don't want to be over zealous, so those individuals get worse. It isn't hard to figure out who are doing it just to be disruptive, and who isn't. The worst offenders periodically will openly brag about how good they are at causing problems on the board.
All the things you mention are derivatives of AmigaOS, so are directly Amiga related. If CUSA produce something Amiga related, we have every right to see it on these boards, and i'd expect to. If they produced an alternative AmigaOS, or an workbench like linux with UAE built in? that would have to count.
Your quite far off the beaten track though, an silk screened logo on an android tablet or C64 PC case bares no relation to something that will run Amiga software, and should not be compared to most of your examples. As an Amigan, i'm quite surprised you can't see the difference.
That doesn't mean there is not a place for these things, it's just people should judge carefully which forum to post them into, and whether or not they are Amiga newsworthy enough to hit the front page.
This is Amiga.org. Not Amiga brand name.org, or commodore.org. The machine(s) that run the OS and software are why (most) of us are here.
As for trolling on the boards,your right, CUSA threads would not be half as bad if our Mods would come down on the worst offenders a bit more often.
