The rudeness comes from London mostly. When you pack people too close together, they tend to develop a bunch of social rules, to keep sane. Those rules are unspoken and dynamic. That also cause an impressive reaction when you break them by mistake. It’s quite common worldwide, but London it particular about them.
Once you’re clear of the big smoke, and get a feel for the lingo and etiquette, we are actually quite a friendly bunch.
That’s still a problem, but it’s not a new one. There’s always been the issue that lights bright enough to see ahead reliably are also bright enough to dazzle. It’s also a lot easier to cope with a quick flash, however, rather than continuous glare.
The issue with a lot of LED lights isn’t brightness, its beam dip. The light should be angled downwards so it never shines into the oncoming traffic.
Unfortunately, a lot of retrofitted brighter bulbs don’t play nicely with the beam dips. Car companies also err towards helping their diver, rather than the oncoming ones.
It looks like a UK bus. If you want to help make the bus company’s life miserable there is a useful trick. This is the sort of thing a lot of parish council members will get disproportionately angry about. They also tend to have far less to do than higher bits of government. They also know a lot more about the inner workings of local government, and who’s ear to burn about it. A politely written letter (or a few from several people) can get them up in arms about it.
Once you set that in motion, wait a week or 2, then also contact the local papers about it. I’ve seen them roll with far smaller stories than this.
Neither group has much/any hard power, but the soft power of the NIMBY croud can be extremely effective against public facing companies.
Edit to add.

It could be argued that that light is a statutory nuisance.
The greyhound brain is like a pressure cooker. If given somewhere to vent periodically, they are fine. They go off like a rocket for 10-20 minutes, then are happy to dose the day away.
This is also why lurchers (greyhound crosses) are so universally crazy. That pressure cooker has a nice big crack in it. It vents into the instincts of the cross. It can be great fun, but it requires some management to keep from being problematic.
I fully agree, there’s some stupid ones out there. But they are actually less common than you initially think.
I spend far too long going up and down the motorways. I get bored and start comparing the various problematic cars. Most lack the nice clean cut off line, or it’s set so high as to be invisible. I’ve rarely been dazzled by cars with a properly set beam dip. It’s either high beams, or messed up beam dip.
