I'm sure we all misunderstood. Surely they will use v7 and keep forking as needed,

Good joke !
The most dirty trick is that they confirmed many times, that with "Atlantis" they change the algo to be ASIC-resistant, after they asked the community to participate in new code testing, and immediately after the testing is finished, they announced that the coin will remain ASIC-oriented. So, dear community, we don't need you any more. Thanks for pushing the project and making it visible, we keep our 2000000 premined coins and we are comfortable with the future emission controlled by Chinese ASIC farms.
All this bla-bla "update from the Dero Project team dated June.24/2018" is a bullshit.
