The guy is mostly correct on the cause, degradation of the phosphor (not phosphate though). But he's wrong in that the degradation doesn't turn the LED itself to UV - that is fixed forever by quantum mechanics factors. See #3 below.
ALL white light LEDs start with a UV LED emitter - we do not know how to make LEDs that emit white light themselves. It's a quantum mechanics thing, there is no band gap that gives out pure white light. In other words, the base LED for white light is actually always designed as a UV emitter. That part never changes. (red, green yellow LEDs are different, they give out RGY light from the start, they have no phosphor. Blue LEDs are kind of mutants and close to UV.)
If you look at many LED lights you will see that the unlit COB LED looks yellowish. That is because there are two coatings on the LED itself. One is the bottom layer over the LED chip; it is a light emitter that takes in UV and outputs white light; the top coating over it is yellow to filter out any UV that passes through. In the shitty Chinese LEDs, they make them with bad chemistry for the top layer and it degrades because any UV leakage actually destroys the yellow dye compound over time.
Interesting read, whats more interesting to me is that this subject has been brought up a few times, its the first time I remember you saying that you work for a led street lighting technology supply company.
I might actually believe you, if this hadnt been going on since at least 2018. While this blog claims 2016, I cant find proof of that. Other than some experiments done overseas. This was a topic that came up many times over the years there in r/conspiracy..... before the sub became pure trash.
I'm okay with your inquisitive perspective, so ask away if you have questions. I do not lie nor bullshit, so it's okay to ask for documentation or verification. I am real.
I do contract engineering and have consulted at about 100 companies in a wide range of fields. This gives me an unusually broad perspective and knowledge background. I work for many companies and apply my background in physics, chemistry, electrical engineering, and computer design. I worked for NASA and aerospace companies. I'm kind of a black swan.
One company was Exclara, an LED lighting company. They made power supplies for LED street lighting. Since then I've consulted at a company that does quantum mechanics modeling for semiconductors (such as LEDs) and for chip manufacturers. So that's where I get my knowledge of factors in the purple street lights.
I actually have some respect for you, so I will not give a snarky reply. Here's my background and indeed, one example:

Wooooooaaaa found this link from this blog, https://dontspeaknews.com/2021/08/27/it-appears-theres-much-more-to-these-new-led-purple-street-lamps-than-weve-seen-so-far/ , in the youtube video the doctor says "a nation full of zombies", sound familiar?
