Titus - although I understand and agree with most of your points, and have posted as much, I wonder if you may be overreacting a little. After all, the flag paint jobs were pretty cheap in the first place. I think you should email Frontier and make your feelings known to them on this and point out this thread to them, and also point out that putting the paint jobs that they were previously selling for £10 each back on the store would be even more upsetting, and then see what happens into the future.
This may be a marketing mis step rather than the armageddon that many of us are assuming.
Fundamentally I don't actually have a major issue with them putting this stuff back up for sale, if they communicate it effectively, and they put out some explanation, or a poll or something, to the fans. If they put a poll up saying we're thinking of making the wireframe cobra available again due to popular demand and we'd like your comments, at least we would feel like we have a voice, and frankly I would probably say I was ok with it. However if they just do it I will be a little annoyed, having previously paid through the nose for it on the basis of a statement clearly designed to imply it was a one off thing (legalities aside).
As regards the offline mode, although it's comparable in some ways, it's in many ways not the same because it's much bigger. I would think that they had to make a decision between putting huge development resources into getting an offline mode working after release, which was probably only really needed by a small minority of customers, or using the resources to support other developments that work for the vast majority of customers. It upsets people in the same way, but I can understand why they made that decision. It was bound to upset quite a few people, but if they had to delay the planet landing expansion by 6 months to finish the offline mode, that would also have upset people, possibly even more of them. They were stuck in a difficult situation. I would also think that if 75% of their preorder customers had taken a refund and said they didn't want the game if there was no offline mode, they would have changed their stance pretty rapidly.
In this situation, they are degrading customer trust for little reason - it's just a few paintjob sales, and with a more clever communications strategy they really didn't need to upset anybody at all.
I am also trying very hard to keep in mind that they are extremely busy right now and they probably don't have time to think of everything. Give them feedback if you're not happy, and email them directly as well rather than just forum posting.
I think I've been reasonably calm and collected through this thread.
I have not threatened to ragequit, demand a refund, do a chargeback or anything people might point at me and say "throwing my toys out the pram".
I've even said I most likely will make future purchases on the store, but whereas before I would go straight to the store and just buy what I could (and over the last few months I've spend nearly another £70 on just skins and around another £100 on physical merch such as the T-shirts, hoodies, etc - because I bought plenty at the premier event - oh and I also paid £53 for the actual premier ticket after postage) now when they say "BUY THIS NOW, £10 FOR ONLY A LIMITED TIME" I'm going to be very, very skeptical.
They have lost a satisfied customer. It would be very easy to get this one back by making an apology and not doing it again, but even after that I'll still be very weary until their actions prove it.
So far today they have actually made it worse by further editing the skins they accidentally forgot to take the 14th September date off, no doubt this thread tipped them off to it.
Like I say, a satisfied customer tells X friends to buy a product or service, an angry customer tells XXXX not to. At the moment I'm a dis-satisfied customer - not at any stage of telling people to not buy the game, but certainly not going out my way to recommend it anymore to anyone.
I'm not here to see Frontier or the game suffer, but I'm not a poor person - I have disposable income every month and so far I'm now looking at spending it elsewhere, where Frontier would have happily got another £10-20 a month out of me if they continued to release new stuff on the store.
