These are diversity heatmaps.
You can not say E-V13 (as a whole, not particular branches that might not apply) is not Balkanic in origin due to it being widespread in all of Europe, and not say the same thing for L283 if you are basing your conclusion on the same faulty logic.

Haplogroup E-V13 is the only lineage that reaches the highest frequencies out of Africa. In fact, it represents about 85% of the European E-M78 chromosomes with a clinal pattern of frequency distribution from the southern Balkan peninsula (19.6%) to western Europe (2.5%). The same haplogroup is also present at lower frequencies in Anatolia (3.8%), the Near East (2.0%), and the Caucasus (1.8%). In Africa, haplogroup E-V13 is rare, being observed only in northern Africa at a low frequency (0.9%).

Cruciani et al. (2007)
According to some authors E-V13 appears to have originated in Greece or the southern Balkans and its presence in the rest of the Mediterranean is likely a consequence of Greek colonization.[22][23][24] Within Europe, E-V13 is especially common in the Balkans and some parts of Italy. In different studies, particularly high frequencies have been observed in Kosovo Albanians (45.6%[25]), Macedonian Albanians (34.4%[14]), Albanians (32.29%Cruciani et al. (2007)) , and in some parts of Greece (ca. 35%[26]).[27]
The TMRCA of European V13 is 4700–4000 years ago.[35] Phylogenetic analysis suggest that the European v13 spread through Europe from the Balkans in a "rapid demographic expansion".[35]
The distribution and diversity of V13 are often thought to represent the introduction of early farming technologies, during the Neolithic expansion, into Europe by way of the Balkans.[12] The haplogroup J2b (J-M12) has also frequently been discussed in connection with V13, as a haplogroup with a seemingly very similar distribution and pre-history.[3][6][12] (There is no consensus regarding the circumstances or timing of its evolution.)"
All this is not news. Out of the blue going reactionary and attributing V13 to non Balkan peoples due to some faulty logic is perplexing.
