To be precise, not all AMD Ryzen stock coolers have LEDs. The Wraith Max, Wraith Prism (successor to the Max), and some Wraith Spire coolers have LEDs.
For first-generation Ryzen, the -X models were often sold without a bundled stock cooler, which limited uptake of Wraith Max. Some had Wraith Spires with LEDs, others without.
For second-generation Ryzen, all CPUs come with stock coolers. The Ryzen 7 2700X has Wraith Prism and the 2700 non-X has Wraith Spire w/LED. The stock Wraith Spire and Wraith Stealth coolers for other Ryzen 2000-series CPUs do not have LEDs.
>>>In one incident, the Carlsbad Army Airfield Auxiliary Air Base (32°15′39″N 104°13′45″W) near Carlsbad, New Mexico, was set on fire on May 15, 1943, when armed bats were accidentally released. The bats roosted under a fuel tank and incinerated the test range.
I got such a delicious feeling of Schadenfreude from this.
I've bought a few things after reading their reviews, but since found a select few youtubers who seem more genuine (e.g. RocketJumpNinja for gaming mice).
