It’s still up to debate who are the negotiators:
The Press Service of the President of the Republic of Belarus said it’s Lukashenko.
Other claims The President's Administration of Russia is involved (names of Kirienko and Patrushev are mentioned).

Dyumin [Tula’s governor who hadn’t conflicted with Prigozhin] is negotiating on behalf of the authorities with Prigozhin and Utkin. The ultimatum is to abandon the idea of going to Moscow.

"The Wagner PMC was planned to be disbanded. On June 23rd, we joined the 'March of Justice'. In one day, we walked almost 200 kilometers without shedding a single drop of our fighters' blood. Now the moment has come when blood may spill. Therefore, understanding the responsibility for Russian blood being shed on one side or the other, we are turning our columns around and heading in the opposite direction, and we are going to field camps according to plan," said Prigozhin.

oh, i see!
i do think that we need “normies” here tho 😤
as a person living in a dictatorship, i can tell how even the most uninterested generic public get tired of government-controlled socials, tries to avoid using them and seeking for alternatives.
with time more and more people realise that – it happens when person’s point of view suddenly becomes not-welcomed in those curated socials. and the stricter government acts, the quicker the transition to uncontrolled socials wilhappen.
now, to all the things people will miss and want from not-controlled socials: those are headaches for creators of nostr clients and apps – they should care of how to make it more intuitive, easy to use, quick and secure and etc.
i have mentioned how people would stay on their theme-related relays – this is how i see censorship issue resolved – because it’ll be the relay problem to manage the notes and decide which one should and which one shouldn’t be posted.
but i liked your statement of “mainstream media avoid platforms with no moderation” - not because i think nostr needs to be promoted, but because it can made it – well – a reputation 🥴
