Nevertheless, severe acute damage, such as hyponatremic shock or delirium, may occur following intense physical efforts and ingestion of several litres of low mineral water (10)."
Bolded the relevant bit for emphasis. It's the "several liters" part that damages your argument. You also conveniently omitted the very next sentence:
The so-called "water intoxication" (hyponatremic shock) may also occur with rapid ingestion of excessive amounts not only of low-mineral water but also tap water.
Turns out that ingesting "several liters" of just about anything is going to affect homeostasis faster than the kidneys can correct it.
The “intoxication” risk increases with decreasing levels of TDS.”
Go ahead and quantify that risk. When you do the math, you'll find that 1 liter of chemically pure water poses the same risk of hyponatremia as approximately 1.002 liters of tap water. Which makes the WHO statement technically true, but definitely misleading.
Neil DeGrasse Tyson's statements are in accordance to what the WHO said.
That's likely true, but you've misrepresented WHO, so I'm assuming it likely you've misrepresented Tyson as well.
