1: please don't colour your text makes viewing on certain themes tricky, specifically elite's default one

2: Frontier is not changing anything, they are clarifying what is already there, they haven't changed the wording or anything, they are making it clear, because apparently to some people it was unclear....
There was made a 'stink' over it as you call it, because it was a deplorable action, and
SDC has exactly the same tools available to them, the tools the game is based around to fight back against those attacking their/your faction, the background simulation, now if you don't want to use those tools, which are part of the game you are playing, that is no one elses fault or choice but yours.
3: SDC are not the first nor unique in the actions done, your group simply did something that made the kettle boil over, on matters that already exist and are an issue, heck there's several threads about the consequences of griefers in open, namely people seeing less people in it, especially those that want to find pvp targets for piracy, so yeah....it is an issue that's been ongoing, but SDC became the last straw.
4: SDC is build around fun, cool, but then I would think that you would know that when that fun is one-sided that is a potential problem?, in general if one party is having fun at the expense of another, that party will eventually have to find ways of having fun alone? and it isn't even that hard to create good interactions and fun for everyone, and no it doesn't need to be care bear or such as gets thrown around not one bit, there just needs to be 'more' to it then, interdict boom, interdict boom.
Edit: and to clarify, there will yes, always be people that want no risk at all to what they do in their gameplay, but I think you will find as creators that the vast majority isn't like that, or at least that's my continual impression on this matter on the forum and with others I've talked to.
