Politicians in America voted to keep permanent DST despite the effects in States with more Northerly latitudes.
Here is the correct explanation for DST.
The fundamental fact is that the human devised 24 hour cycle is anchored to the natural noon cycle.
When timekeeping and the sunrise/noon/sunset are set to their normal sync, the length of time from clock sunrise to clock noon is symmetrical with the length of time from clock noon to clock sunset.
What DST does is break the symmetry, where 1 hour from clock sunrise to natural noon is subtracted and transferred to 1 hour between natural noon and clock sunset. In terms of clocks and the 24 hour cycle, everything moves forward by an hour-

Just pick up the Sun and move it back 1 hour to determine the DST asymmetry where 'longer evenings' result.
It is advisable to work with timekeeping alone and just leave natural noon as the anchor and this is where the authors of the article jumped the tracks.
Theorists and academics have gone on a misadventure with timekeeping for the last 250+ years and it shows in the comments as people try to figure out the flexibility of timekeeping in relation to the day/night cycle and the rotation of the planet behind
the effects.
