Let's put it like this: recently Something Awful moved their entire Games subforum behind their paywall. This was roughly two weeks after CJ snapped and started inserting DRM into Railcraft.
I'm guessing the SA admins were getting sick of all the guest activity around specific threads and the Twitter drama related to it in the past month, probably for other games as well as the Goons are consistently infamous over in Eve Online too. Lest we forget, once long ago, Technic was supposed to be a private pack. The Yogscast, being Goons, found the pack and showcased it in a five-part YouTube series. That's how this all started. It's why FTB have their permissions based private pack system to avoid a repeat of the situation. The Technic Platform is a continuation of the "I just want to play the game with cool mods please" mentality that caused Technic to exist in the first place.
All of this mudslinging boils down to fundamental differences in ideology between multiple parties and them clashing badly.
Edit: As for Tekkit Classic, that version of the pack is about a year old. Messing with it would hugely inconvenience owners of large servers and that is and has always been the focus of Tekkit Classic - to support large-scale Minecraft servers with mods. The pack and ideology behind it put server owners first above everyone else. It will not get changed until T-C updates for 1.4.7/1.5 and expecting it to or even that it should is silly.
