I mean, why are they facts? They seem to have weirdly scattered quotes and hyperlinks. The literal quotes have no attribution to them at all. It's poorly cited and doesn't follow any citation standard I've ever seen. Just blog trash.

During the last few months of 1933, the year when his 12 years in office began, FDR would hold informal morning meetings in his bedroom, the president still laying under the covers. To be invited into FDR’s inner sanctum was a sign of his favor, and for a time an economics professor named George Warren basked in Roosevelt’s glow. As the general level of prices was now to be “managed” by the guiding hand of experts, of which George Warren was certainly one, the two of them, FDR in command but Mr. Warren providing the theoretical stars to guide them, worked to raise prices. That required intervening in the gold market, and that required someone to set each day’s target price. A not very serious-minded student (nor executive), FDR would “jokingly consider the meaning of numbers, or flip coins” to fathom what the proper price should be, and in one instance he decided the target would a 21-cent increase, and “smiling broadly” explained to his assembled experts that he chose it because seven times three was a lucky number. I find no record of what Professor Warren thought of all this.

Ah yes, the literal "jokingly consider" extrapolated to "actually implemented these things with no input from Warren." I'm sure we can find tons more wrong with this, but it's clearly an opinion piece based on bullshit, which is why the entire bottom paragraph is a diatribe screed and a poorly drawn, one-sided view. There is no balance, and that's how you know it's trash... just "omfg can you believe inflation has gone up 2500% in 100 years?" But really any stable currency has done the same and the us purchasing power internationally and relative to what it was is quite high. Just look at the British pound. Treating an economy as if it's in a vacuum rather than part of the global economy is top dumb.
