Do you think they...
1. ...acted honest?
2. ...did not lie?
3. ...delivered their promises?
4. ...are as transparent as promised?
5. ...are open for discussion?
I can't answer 1,2 and 4. Partly because I'd have to do some analysis and partly because I'm not sure I (we?) have enough info to determine the answers. Can you provide an example of something specific to get me thinking?
I may not be interpreting your question correctly, but no, not 100%. For one, PoW ended much sooner. Some deliverables have been shaky but there is no way that I can jump to the conclusion that they intentionally misled anyone. Problems with rollout can easily be blamed on shit going wrong and people leaving. Executing big projects is hard even if you have a perfect strategy.
Are they open to discussion? Yes, I think they are to an extent or at least were at one time. If you are being fair, you have to admit that not all of the contents of this thread qualify as "discussion." I think people have their limits but at the same time I'm not delusional enough to think they executed communication perfectly.
Some examples:
They say in Terms and Conditions:
The Company, which is solely responsible for conducting the Presale,
will use the proceeds of the Presale to acquire NeuCoin Tokens from the NeuCoin Foundations immediately after the the NeuCoin Tokens are initially created and the NeuCoin System is made publicly available (the Public Release), expected to occur in the summer of 2015.
The Company is not authorized to use the proceeds of the Presale for any other purpose. All the BTC raised in the presale will be kept in a publicly visible multisig Bitcoin address which will be published on
www.neucoin.org.
Private keys will be held by several members of the NeuCoin Project Team along with a representative of the Company so that the Company will not be able to transfer funds from the multisig address without the consent of the NeuCoin Project Team members. Immediately after acquiring NeuCoin Tokens from the NeuCoin Foundations, Company will distribute them to the Purchasers. If the Public Release of the NeuCoin System has not occurred by September 30, 2015 (the Release Deadline), the Company will refund all Purchasers their entire purchase amounts as described below. The Company will be liquidated shortly after either distributing NeuCoin Tokens or refunds to all Purchasers.

Who holds the priv-key and who is the representative by the way?
Transparency and Governance
NeuCoin will be open, accountable and ultimately controlled by coin holders. NeuCoins core code development, user growth programs, and projects to increase utility will be supported by three non-profit foundations based in Isle of Man: the Code, Growth and Utility foundations.
All foundations are ultimately controlled by NeuCoin holders (1 NeuCoin = 1 vote), who have the power to hire, fire and set compensation for the foundations Council Members, and have a right of approval on annual budgets, spending priorities and other matters. This structure makes NeuCoin more decentralized and accountable than Bitcoin, Ripple or Stellar, let alone most of the anonymous alt coins out there.
http://www.neucoin.org/en/terms_and_conditionsDid that happen? Would you say the foundations are controlled by the Neucoin-Holders? Was there a voting? Coin-Holders "have a right of approval on annual budgets, spending priorities and other matters". Would you say that's true?

I joined the community and was very much active and enthusiastic. I bought in the presale and even came up with the Squirrel name- Tippy. They made me moderator and all was good and exciting. Then they started pushing back the release and then investors in the community started asking questions. Priemievalsoup was a big investor and he started asking some serious questions. Being a game developer and having some experience with releasing products, his question on why there was no testnet really struck a chord for me. I asked Sandrine and the other moderators about this, and Sandrine told me the team was doing extensive testing already, and a testnet was not needed.
Fast forward a month later to the supposed launch- they come and say they are pushing back the launch because they need more testing and are releasing a testnet to the presale investors by the end of the month. I was really set off and finally had to leave when the end of the month came, the testnet was not released to us, but they claimed they held their promise because they released to "angel investors."

Or the funny fact that they did not, like promised, release a Block-Explorer right from the start! Without the unofficial one nobody would have known about the fact that >99% of all coins were in the Top 100! And that's weird because they said that there were >1000 pre-sale-Investors. But more than just 3 billion Coins in the top 100??
