I'm not sure where the click-bait is. The title of the article is consistent with the content, i.e., many beverages at Starbucks have a lot of sugar content. Whether that comes from adding sugar or adding ingredients which are naturally sweet is not the point of the article.
> It's probably important to note that it's not only "flavored" drinks, milk has quite a bit of sugar in it naturally,
True, but is milk the sole responsible for the high sugar content in a latte?
> the "special" milk which is used by some coffee places has about 9% fat and 2-3% carbohydrates which makes it worse than coke on it's own,
Well, if "special" means "processed", then this again proves the point of the article. No matter where or how the sugar is added, these drinks have quite a lot of it.
> skimmed usually have higher amounts of sugar to make it not taste like well the water it is
Confirms the point above.
> It's also probably worth noting that a Starbucks "Venti" size is more than double the the volume of a coke can to begin with so about 680ml (espresso shot which is used as the base is only about 30ml) of milk + couple of sugar spoons to make it sweet can easily get to 2-3 times the amount of sugar in coke
Perhaps not for the same volume. Many fast food chains sell sodas in cups that are 2-3 times the volume of a 33cl can.
> without even having to go overboard with crap like whipped cream and syrups.
Again, consistent with the article's point. The numbers are there, and they seem to be higher than the recommended daily amount of sugar intake.
