Yeah, this has Sally Albright/Correct The Record/paid Bidenbot hack attack against Leftists written all over it.
Basically, their job is to keep "progressives" trapped within the Democrat pigpen by smearing any criticism of Biden and the Democrats' right turn as "Putinist", "far Leftist" and against "democratic outcomes".
And his beef with you is a long-term vendetta.
I figured that Bidenbots would, once Bluesky opened the doors to the Fedi, bring their smears here.
