You obviously seem to have something against that.

It's factually correct. E1b-L618 is an Ancestral African derived patrilineage and was picked up by farmers en route to Europe. It represents a minor African patrilineage signal in farmers.
J-L283 is a CHG-related steppe patrilineage and its quaternary ancestor, the oldest "J2b2" sample, is a Caucasus Hunter Gatherer from Kotias Klde. The dynamics are totally different to E1b-L618 and its path to Europe. The Caucasus is a transcontonental region of which a part of it is located in Europe and the other part borders continental Europe.
CHG ancestry is attested in Eastern Europe since at least the Mesolithic and it did contribute autosomally and uniparentally since then in different proportions to populations of the dry steppe. The oldest J2b-L283 sample is a Core Yamnaya sample from the Western Steppe, Moldova. We have older aDNA attestation of J-L283 than E1b-V13 so that last sentence doesn't make much sense. As is labeling J2b2 or J-L283 "Middleastern".
E-L618 likely arose in the Levant and no, there is no African signal among the farmers.

And the CHG ancestry you are talking about in Mesolithic Eastern Europe has absolutely nothing to do with J-L283. In fact, it's getting more and more likely that the path of J-L283 to Europe started at the very EBA or very late Chalcolithic from the North Caucasus.
No African patrilineage signal? M78>L618 is the African patrilineage signal. E1b-M78>L618 just like its brother V22 represents a Northafrican patrlineage. E1b-M78>L618 is not an original farmer lineage. E1b-L618 itself represents a migration from Africa to the Levant. It's a secondarily acquired patrilineage that was overall rare amongst the G2 (H2 etc.) rich farmers.
At the very early EBA? You do realize that with the Moldova sample that's already an inaccurate claim and doesn't work time frame wise. His auDNA is labeled core Yamnaya. When the quaternary ancestor of L283 was hunting and gathering in the Caucasus E1b-M78>L618 was still in Africa. And the Caucasus is, as I have said before, a transcontinental region.
Saying that CHG-related auDNA and patrilineages are attested in Eastern Europe since the Mesolithic is an important point to make. Regardless if one postulates that L283 was amongst the very earliest or the "later" Neolithic, Early Chalcolithic CHG waves.
