As EK articulately said before me, it does not matter what happened to any collected funds before - why? because the intent of these funds (which where collected under the label donation - as to no promises made for funds sent) was to facilitate the development and creation of the Elastic system. Now we are more than a year later and we are almost at the point of releasing a working system (this will happen, not guessing). What can you learn from this you may ask? well, you may learn that the project is reaching where it was headed for, and manged to pass so many initial goals/wishes. The funds issue is irrelevant because we are arriving where we wanted to be (with or without funds).
This issue has been discussed to death before and it exists in threads and old posts, therefore, I suggest eliminating any further discussion about it as it only brings more dust into the clean air we wish to have here.
Let me say it clear, if I put money in any project out there (and I do), I would pray for them to arrive to the state Elastic is in right now in many regards, even with 100mill funding behind them. It is that simple, for those who use their brains to think and their eyes to see what is going on around them.
