Here is the link of the old Constellation thread:
https://bitcointalk.org/index.php?topic=3131610.0
I also do not understand why there is a new announcement thread, but there are interesting comments that the Constellation team has not responded to, I will bring them here, maybe someone will respond from the team:

I saw that the founder Brendan Playford, the CEO & Founder of Constellation $DAG as left the project and I logically ask on telegram the reasons. This
earned me an immediate ban.

I do not say it's a scam, but I have seen these methods of responding with banns only in shitcoins or scam projects.

The community is also very virulent, one of the worst I've ever seen...

Their only argument that they concluded a deal with Air Force, but advertisements and partnerships make not everything, like UnionPay with HPB or the
British islands with LIFE, it does not prevent the project from dying.

But watch out with this "deal" they just joined a program like many other startups https://www.afsbirsttr.af.mil/

The news is oversold by the team, but the market never lies. It would be the partnership of the century but the project remains in microcap and this from
years...

Personally, I prefer to remove everything from this project, too many redflags, we have no transparency on the team and the methods are worthy of
dictator communism

I'll let you ask the question or make your own opinion or argue here.
