Noone denies that it was a technical problem.
Good to know what exactly is an issue and it is good the team disclosed it and took investigating it seriously.
It is the solution that disappoints, though. Your actions simply state: you can not trust our system (or: you should take 100% risk for using our system).

Nothing illegal with that of course.
But it's like with the exchanges Many of them them encounter a technical issues (sometimes hacks, sometimes simply malfunctions).
Some of them are helping their users recoupl their losses, and some are simply saying "well, it was a hack/technical issue, you took the risk".
Too bad that Wings chose the latter path. As I said before, I was not personally affected since my tokens were on the exchange anyway, but I was affected indirectly, because the way this was handled hit Wings's reputation and perhaps indirectly resulted in further price decline.

You can do as you wish, but probably best action here would be:
- apologise instantly
- figure out how many funds were lost and by how many people
- use some of the project's funds to pay back people who lost money because of your bug (you have millions guys, those loses were probably tiny compared to that)
- launch full and transparent internal investigation and publish it's results

You chose different path and you have right to do so, but the crypto community has a right to judge you.
I guess the market in the following months will decide if it is fair in such circumstances to simply blame it on technical issue.

IMO the trust in the project is lost now after all that happened (weird direction with free listings with no rewards, then funds locked in smart contract, then disappointing solution to that).

I will not comment on this matter any further, but I could bet that the following will happen now: the team will continue to ignore the bad PR that this whole thing brought to them, they will continue open sourcing the project (which is good), but they will not spend any money for relevant things like paying people back or marketing or sponsored forecasts etc., they will wait couple of months for people to forget about the projects and they will move to other ventures (which is understandable and standard in startup business, but you should guys at least try fixing that before you move further).
