I just dived into that rabbit hole, heres what I could understand until now:
-
Theres this Business guy, who owns/Controls much of the Calyx Infrastructure.
-
When Copperhead, a for Profit Company tried to buy up Graphene, the Calyx Guy was (according to Graphene Mastodon team) very prominent and they tried to pressure them into buying it up
-
Now it backfired for Calyx as the Business guy did a

-
On the team, and now they have to change all the Infrastructure and Keys in order to make their workflow secure again
-
Louis has a Telecom Company with that dude as co-founder, apparently according to some legal document
-
Also, very many other OSs have a Problem with Graphene, as they want to be the next Private ROM, but they just wont put in the Time to do anything more then fork Linaege and add their own Propriatery stuff (looking at you, Iode), so they very often try to make alligations against Graphene, only to be completely wrong
Tbh, I just dont get ROMs, just because you cant beat Graphene dosent mean that everyone needs the kind of Security Graphene gives you. Just dont fuck up, no matter how hard it apparently is.
