This might be a very long comment
We are all here for different reasons! Some are here for the money, or a part of it, some are here for the interactions, the community, etc. So you have to make the best of all those different interests, incentives to build a platform like steemit.
Who is suppose to support the develpment?
The community. Mainly the community. We are in an open source environment. You can't expect a company( which is for profit by definition) to provide services without a business model. Note: this is why it is a bit weird with blockstream and bitcoin. Steemit, Inc make the choices that interest them. I am among the opponents of the SMT, because I think they will dilute the sense of community and the strength of the network.
The community support means everyone, with his or her capacities, can help the platform gets bigger, better. Some have technical skills, some have communication skills like you. Of course I believe that we should be able to help on the top of steem rewards but the reality is that you might not get. You might not get noticed. The #french speaking community has been more and more active, same for other like #cn and #kr. But steemit is very hard if you don't interact in english.
You are entitled to be sad not angry
as I am very happy to see the level of support you get now on your post. We don't know the personal life and implication of everyone. I, for instance, am a witness. Since I am a low ranking (0.25 block/day), I am losing money being a witness. I do it for fun, for education, to help on security and not because of some ROI. I just go 100 Steem for Witnesses Below Rank 80! as part of @jerrybanfield #budgets. This means I can keep my node running longer and start writing on other part of the #ecosysteem.
We can get better
Witnesses for instance can be involve more, much more than whales that I would vote to leave alone. But the community, as a whole, should be aware of that. We have a marvellously easy way of crowdfunding: post an article and ask for vote to pay for whatever idea you are proposing.
