I too was surprised to see the post that Coke is too sweet compared to Pepsi as I've never heard anyone say or write that before. I've always heard people say Pepsi is sweeter than Coke. Apparently that was one of the main drivers of "New" Coke back in the 80s, to make a sweeter version of Coke to compete with Pepsi, especially the Pepsi Challenge, which rewarded sweetness due to the small sipping size. The person you're responding to may have had a similar lifetime experience and that's why they commented on it. Likely not nefarious, simply an observation on something unexpected.
