@anthonws: MikroTik already has that... kind of. Description of this forum is "BETA Testing and Feature Suggestions for the next RouterOS release (ROS v7)", so you're welcome to post your ideas and people do so. Others comment on it to show their interest. Only the actual voting is missing. Oh and also MikroTik's interest, it seems. If there was voting, by now we'd have OpenVPN (*) on top with 10k votes and it would be sitting and waiting as it is now. So that's pointless.
(*) Actually, OpenVPN it not that important by itself. It's not THE killer feature and after such long time, anyone who needed it probably already found different ways how to satisfy their needs. It's more like a symbol now, even though it would still be nice to have.
Personally I'm a little bit skeptical about these "user voice" things. You have product used by millions and then decide what to implement based on hundereds or low thousands of votes. And you don't even know how many are from people who just came by and won't care a month after. Even from user perspective, nobody is going to browse through thousands of ideas to find good ones. You'll post yours, give few additional votes to some popular requests at the top that you also like and it will be most likely it. So how much these things can be trusted, that's a question.
What's available today is not close to any proper customer engagement. Like you stated, I can go there, ask for a feature, and have millions of people go "+1" without changing anything. Not even a mere reflection of a decision from Mikrotik. Even if it's "Will not be implemented".
I work in a company where everything related to User engagement is vital for the development of our products. We actively scout and research what and where to invest next based on multiple indicators, including platforms like UserVoice! It's thanks to them that our customers (the broader market) feels closer to the decisions being made and also that they are heard. Without the need to be a S400 and have strategic (direct) relation ships with our product teams.
If OpenVPN will never be implemented, then someone should officially state it and make sure that information sits in a place where's visible and related to the FR.
My 2 cents,
