Business 101 teaches us that a company that prematurely announces a spectacular future product or feature will lose out on current sales as buyers forgo the current offerings [Osborne effect]. Cash flow dries up and investors become worried. Share prices fall. Then, if as is likely the future product is delayed for any reason, the death spiral kicks in.

Though that might be true, having absolute no communication is not good either I believe. There are examples that show announcements being effective and it is really not that difficult to understand. The main reason why they are effective is that they are accurate. In other words, if I, as a company, announce that content X will arrive at DD.MM.YYYY at HH:MM and I deliver that as announced, then my customers would likely be happy as their expectations are met. If I do that regulary, I build up trust with my customers as I am a relyable company that rarely fails to not keep the promises made. Wit hthat trust, I have a good foundation to build on.
However, companies failing to deliver what they have announced have a fragile foundation and obviously people become skeptical. Furthermore, having no communication/announcements/transparency results in having zero foundation as well. It also tells me, as a customer now, that a company is not able to keep self made promises in the first place -> unprofessional and unrelyable. Hence I will hold back with my money and time investments.
Same with ED now. We have absolutely zero information on what is following after the beyond series and even if they'd announce something I'd instantly subtract 50% of the content they announced as FDev have shown unrelyable in the past (countless delays, bugs surviving for years, ignoring of the bad connectivity state, content withdraw like carriers and ice textures, etc.). With that knowledge it would probably better to get back announcements (like the weekly sneek peek we have been promised after the release of 2.0 ...) and actual accurate announcements with promises that are kept. This will raise the relyability and my trust which results in my investment.
but completely refusing to communicate is not a good way to make me confident that this game is a good choice.
