I've read that they've made changes which will eventually result in the customer support queue being reduced to a manageable level & then stay there... but "eventually" isn't good enough. It needed fixing yesterday, not months from now. And then a very public apology for messing-up so bad, such that some people might actually forgive them. The longer they take to fix it, the less people will forgive them, and more people run into problems in the first place.
Unfortunately Frontier's general approach to PR (shoot their PR guy now) is to publically ignore bad stuff (at least until it's resolved), in the hope it will go away, or at least not blow-up in their face. But that only works when the situation isn't so bad that it isn't blatantly obvious there is a problem, or it works if your name is Apple. Or worse, they try to frame bad things (no offline mode) as a good thing (minor benefits that felt like they were trying to bribe us). The alternative (which they've shown no sign of doing since the Kickstarter) is to actually be honest with their players, admit ASAP to known problems that affect a lot of people, and give frequent updates to say what they're doing to try to resolve the problem(s).
Maybe they have some over-the-top lawyer stopping them being honest, but if so I think it's rather misguided, as it will tend to result in the opposite of the desired result: It's human nature to be suspicious that other people might be lying & trying to take advantage of you... So if you aren't honest about issues (e.g. fob them off or ignore them) then sooner or later people will assume you are doing bad things intentionally, and so consider taking legal action (as well as telling other people how terrible you are). OTOH, if you explain the problems you are having as early as possible, and give on-going updates explaining why you're having issues resolving the problems, then people tend to believe you, and most will be willing to accept problems for a long time, as long as they think you are honestly trying to resolve it. I'm pretty sure the lack of offline mode would have been almost a non-issue if they've raised the prospect of it's loss 6 months earlier, rather than dropping a bombshell disguised as a bonus at the last minute.
Many Kickstarters show exactly these issues being played out - most Kickstarters stay silent about delays & problems, which results in the majority of backers being really unhappy & swearing never again to believe a word that comes out of their mouths... but a few Kickstarters publically discuss problems as soon as they run into them, which results in most backers being understanding & willing to accept delays & other issues. I've also seen the same happen outside of Kickstarter.
Maybe there is a misguided view that being silent about your problems & mistakes is being "professional", but IMHO that is a wildly outmoded view, which has been made irrelevant by the internet (everyone can see that they aren't alone in having a problem), unless you are one of a very few very large companies. Frontier isn't.
