The complete quotes in the marketing (the article made the odd decision to quote PART OF the caffeine description out-of-context) are:
“Plant-based, clean caffeine powered by guarana & green coffee extract”.
and
“Plant-based and Clean with as much caffeine as our Dark Roast coffee”
I would call that marketing accurate and correct. Except one thing… It’s a fact that one ounce of their lemonade has significantly less caffeine (about 2/3) than one ounce of their dark roast coffee, and dramatically less than their light roast coffee. Could you have guessed that from the quotes? Because my first point of note is that they’re incorrect about it having “as much caffeine as our Dark Roast”.
the large Charged Lemonade has more caffeine than any size of Panera’s dark roast coffee
This is also both misleading and carefully worded. It’s comparing a 16oz cup to a 30oz cup, both sold with unlimited refills, and leaving out that the Charged Lemonade is not even the highest-caffeine item on the menu.
I would say the article is factually wrong and misleading. The problem is, we don’t know the full details of the complaint, which might actually be valid. The article, however, is not doing it justice.
