Trusting on people that admit stuff can be as much deceiving as the other way around.
Admitting or not, can help or not the community, depending on what actions come after that. As any other STEEMian, being watchful is advisable (as much as you can), I have seen much admitting sometimes.. but then nothing get's done, and that's not useful too.
Being a witness is not just about trust unfortunately. They almost need to be "gods" these days, in order to keep their positions, talking care of any sorts of "obstacles" that flow within the community, sometimes even fraudulent with vengeance principles. I know no one is perfect or that they are not all "angels"... but from the perspective of going forward, what I least expect is for them to keep "admitting" whatever they do wrong.
Would much prefer that instead of admitting the previous code did not handle some kind of governance impeccably with 0% flaws (which is kind of going to the extreme here, but let's consider it), that they instead proposed new code changes already tested on the testnet and how would those changes improve the current problems found on governance. And then get this ASAP into the plans... so that people can start looking that "things are being planned, and eventually done".
I don't want to go that deep on that conversation now because currently things are not normal. The governance is somehow "challenged" by not cooperating parties and until that gets properly dealt with, the things I mentioned above can't flow as fast.
But once they do, then it would be something giving me motivation to buy even more STEEM. And don't get me wrong, I still understand that many changes are in reality experiments. That's why things need to be tested and we should also have more agility into the pipeline of development of STEEM, which by itself it's another whole conversation/topic. Most people that develops on STEEM never get a return for their time spent at least... if you have to compare with real life jobs I mean. It's usually a very long term investment, in average if not way above it, I am guessing.
