I think that is a bit harsh.
We all know why 4Sevens stopped giving us information - people were immature when things changed (design, timing, etc.), so they decided to only present a new light when it was ready to ship. That is our fault as a community.
They also told us why the 18650 body was discontinued - slow sales. They are still a business, and need to find new ways to grow and make money. If they don't, they won't be able to survive, so we need to encourage new manufacturers like 4sevens to gain a larger general market share.
No one but them knows why they decided to discontinue the Revo line. I can only infer that it was a tough decision for them for quite a while simply because their responses kept changing. I am sure they had to weigh multiple factors, and it looks like they decided to stop production of the Revo lights. It is definitely unfortunate since I do like the two SS ones I have, and I will definitely be holding on to them.
We can only make inferences and assumptions as to why they do what they do. In the end, we all need to decide with our wallet to communicate to manufacturers. If there is a light that you want to keep being produced, then you need to buy it, and encourage others to buy it. If there is a manufacturer that you aren't happy with, then stop buying lights from them.
That is the message they got for the 18650 body, the RGB, and potentially the Revo (again, we don't know all the details).
For me, I am quite selective with my lights. I do have many 4sevens lights (not all, by far), and I like to support new manufacturers when I can, especially when they are local (I live in Atlanta), and I buy lights for specific purposes that make sense for me and my situation. I will probably never buy the S18, and that's ok to me - I have an S12 that I thoroughly enjoy, and I will continue to buy from 4Sevens and other manufacturers that produce lights that I desire if funds allow.
