Give them a break. It's a pop science article. Such articles can describe 1.5 concepts at most, so having used that budget on p-values, it's not available for Bayes, so explaining the concept from a frequentist perspective is reasonable. Also Bayesian analysis (as a mainstream stats technique) is relatively new as it has only become mainstream with the advent of cheap computing power.
