The truth of the matter is that this issue is not important at all. It had little impact on the game experience, and no impact at all to any functionality. Yep, it got lots of votes because it was just annoying (I voted too), but not because it was an actual problem of something broken. Then unfortunately Asobo made it important by promising to deliver this simple change in the last patch, then didn’t.
The fix to remove “press any key to start” was what is known as in the IT support world as an “Easy Win” That is, the original function served no purpose, the change has little impact, the change is simple to implement, the change affects everyone and most people will be happy its gone, but no-one will be unhappy its gone. A win from every viewpoint. Unless you promise to deliver it, then don’t.
This unfortunately casts doubt over all the good changes they had made as well. All much more important than the “press any key to start” removal. It is normal then to think “If they got this wrong, then what else have they got wrong.”
Personally I found the “press any key to start” annoying and was happy to see it go. But if they said they were never going to fix it, I wouldn’t have cared much. And as far as I can tell there has been no official comment on what happened to this fix, which hasn’t helped. A missed opportunity for Asobo to do some damage control.
So this issue is not important, but caused a lot of unecessary negative comment, justified or not.
