Focus on "right-wing propaganda" is important enough to be included in headline, but never mentioned again. Suggests to me that this article is scaremongering. Do you really think any organized group isn't using social media automation at this point, be that left or right?
Why would that be your take away?
It's in use by the BJP, which is the right wing party in question. You say it's not mentioned again, but the article has 14 other mentions of the BJP, so your statement is incorrect.
