For me, it's all about their lack of communication.
I bought into the game a little while after the launch on steam and I've been enjoying it (1.2). It felt like the Elite of old where I could get by trading or try to fight and get horribly murdered in my underarmed sidewinder, which was fine. Elite has always had a harsh learning curve.
1.3 rolls along on a friday afternoon no less, and it's a complete bug ridden mess with minimal staff on hand to try and fix the inevitable patch day/expansion launch issues. That Friday and to some extent, the saturday, the game was almost completely unplayable. The issues were eventually (mostly) fixed during the following week day but it just screams of terrible community management.
Despite this, I still enjoy the game even if everything about the game needs a lot of polish ; core mechanics need a lot of work, such as missions not rewarding proper amounts of reputation, ranks not being achieved with advancement, or the servers randomly dropping out whenever there's a heavy load.
They need to dramatically improve their relationship with the community they initially sold their product to before expanding into the next market if you ask me.
Possible solutions.
1. Road Maps, dev blogs and expansions.
If you want your community to continue to stay enthusiastic about your product and the direction that you are taking, you need to let them know the general direction that you are headed. Lets take an example of this - currently, I have heard rumours that landing on planets and interactions on the ground are in the works - this is great, I always loved that about Frontier.
You don't build hype and enthusiasm by keeping secrets. If you want to keep your community interested in the future of your product, you are going to have to give out teasers of what is coming and build up the hype as your product takes on shape. One announcement at an outdated forum designed to showcase the Next Electronic Jesus™ is not keeping your community informed. It needs to be constant interaction and not just near stoic one liners that you are 'working on something to come'
The problem with this is there's no information on when this feature can be expected. If you go and give a general roadmap of when you can reasonably/roughly expect this feature to come then you have a reason to remain enthusiastic and something more concrete to look forward to than 'eh, we're working on it.
2. Proper community management.
Hire staff that know how to interact with the community, or even some of the community itself to hype the game. Devs and owners are not good at this aspect of the business and always have the potential to take critisism of their work harshly. Their passion is great but it can be detrimental to have them snap on, say, twitter like past incidents have proven. Hire people that can sort through all the community feedback and sort out the constructive critisism from the trolling/moaning
Having a member of staff that is both in contact with the Dev team in order to stay informed about recent work, and in contact with the community to help build enthusiasm and hype for those coming features would greatly aid the image of the company and ease a lot of the concerns that are being raised by your customer base.
I personally feel that moving elite into a cross platform situation is a huge mistake given the amount of dumbing down a console port will require - PC's are already far ahead of what an xbox or a PS4 is capable of and you can see evidence of this in the Triple A console market. Equivilant games released cross platform vary wildly in quality, or the pc versions are neutered in order to bring them down to the same level as already obsolete gaming hardware.
It concerns me that Elite will recieve similar treatment.
In short ; You've set the precident for walling off content on a platform basis and it worries me.
