Yeah, that’s fair, I did not have that context originally. I should have quoted the article I linked, because the salient parts point out that it was strange the graffiti evoked the Israeli flag, which I had noticed originally:

Also the message in the medium was confusing. Conceivably a blue Israeli flag, or what immediately evokes it, could be seen as a pro-Jewish sign. Surely any genuine antisemite would have found a clearer way of expressing their hate.

I’m inclined to agree with the BBC’s conclusion:

As for the purpose of Operation Star of David, like all dezinformatsiya it seems to have been to sow confusion and anxiety. The fact that the symbol could be either pro- or anti-Israeli made it all the more interesting: that way both sides would be suspicious.

I notice the Times of Israel doesn’t consider this months-old information when continuing to reference it as evidence of anti-semitism.
