Are Price Comparison sites biased?

>Nah! Sorry to spoil the gossip, but it isn’t us. We’ll be talking to the Junglee team to take down the listings, and hopefully finding the culprit :)

The truth is that sites like Flipkart and Myntra are actively trying to avoid price comparison (Myntra is now app-only), so as to discourage customers from looking for cheapest prices, and settle on brand loyalty instead.
Similar thing happened to mysmartprice as well, when they werewnt showing flipkart.
You don't necessarily need permission to display an offer but you do need a relationship to get a commission on the sale. These relationships can either be brokered through so called "Affiliate Networks" (most common) or when a site gets big enough they could be direct business development deals with the commerce site's marketing team.
It is a low profit business segment as it is (you have to generate a lot of volume to make serious money) so diluting it by including non-commission websites is not very common.
It is, however, somewhat common to list higher commission products near the top of the list. This is a poor user experience so usually it is only done if the two offers have the same price.
