I think one thing to say following this is that it makes sense FD will do what is best for the company, although it always seemed to me like this was a passion project for Braben, and therefore perhaps some decisions made not in line with what is best for the company.
Regardless, in that case, if they think its worth keeping ED going (which seems to be the case) and its profitable for the company, then they will be doing the best they can to maintain that. If it was a ball and chain for them, the best thing to do would be to drop it, or at least put it into maintainance mode and keep the servers running on minimum, or perhaps make an offline patch. This does not match with the upcoming fleet carriers and announcement about the 2020 update.
The logical conclusion to this is that FD are trying to do their best and believe they are doing the right thing, with some admission of mistakes made and areas they can still improve.
Assuming management want to make as much money as possible from ED, they are looking at their sales and reports from players, feedback, etc, and then taking decisions. They have been doing this for years.
The result is what we have now. Buggy updates and complaints about lack of communications.
Let that sink in for a moment people. We've had 5 years of buggy patches, complaints about lack of communications, and numerous open letters and disucsions on the forums, and yet it never changes.
While FD are probably doing what they can to improve processes, expecting this open letter to have any different result to anything in the last 5 years is being overly optimistic at best. They obviously think that in general they are doing the right thing and that thing is still generating them money.
So, despite buggy releases, Steam review bombing, open letters, complaints, etc, they continue to do well as a company, and ED remains fairly stable in terms of players year after year, which is quite interesting in itself.
I have to say I'm a bit surprised to see such a critical post from you. Not that I disagree.
