From the first section:

Under the test, burgers, Frosties, and other menu items will have “dynamic prices,” costing more during times of increased demand.

Don't get me wrong I have a short attention span too but if you're gonna toss negativity around maybe finish the first paragraph? But also how did you get past the first sentence?

The price is what's dynamically changing on those boards, you realize

Here's the statement from their CEO Kirk Tanner (emphasis mine):

Beginning as early as 2025, we will begin testing more enhanced features like dynamic pricing and daypart offerings, along with AI-enabled menu changes and suggestive selling,” he said. “As we continue to show the benefit of this technology in our company-operated restaurants, franchisee interest in digital menu boards should increase, further supporting sales and profit growth across the system.

Here's the Oxford English Definition of "dynamic pricing" since 1929:

the practice of varying the price for a product or service to reflect changing market conditions, in particular the charging of a higher price at a time of greater demand.

Referring to reporters, investors, and consumers as "shitty" for taking a company at their word is just silly.
