It can't be that what he meant, since if you can adjust the vertical angle, you can stop blinding people.

I know. I nearly ran over one who had no good lights, dark hoodie with no reflective gear, when I was reversing on a dark street, at night. Nearly shat myself after the close call.
I know students are poor, but God damn man, your life is worth more than a couple of Euros you're saving by running a crappy light who's battery died 2 years ago. Skip on a pizza/few beers in town one time and get a proper light.
You don't need to spend thousands of euros on gear to have a safe and visible cycling experience.
People are just stupid and lazy about their own safety, that's all. You only realize it when you switch from a cyclist to a driver, how dangerous these cyclists with no good lights are at night.

Dude, that light you shared is a luxury compared to what most students I see have. Most have these god awful things with low battery: https://www.alibaba.com/product-detail/Bicycle-Accessories-S...
Speaking for my German bubble, there are roughly two types of bike riders: those who invest 1k+ on their gear and those that buy a flea market bike for 100€ and then fit the cheapest light they can find (that is, the ones I mention). Most students I know fall in the second category, making those lights quite popular.
