That's a very interesting ( and disturbing!) video.
I have three GU10 fittings in the house each with 4 bulbs. The conventional bulbs lasted a very short time before expiring like flash bulbs! A couple of years ago I therefore took the plunge and purchased 12 x GU10- LED bulbs as replacements. I have experienced no failures with these and light output is still fine. Following your post, however, I quickly went round and checked my bulbs. All these are totally enclosed in a glass envelope and no metal parts are accessible. Big sigh of relief! I think it is another instance of " You pays yer money and makes yer choice" The ones I got were certainly not cheap – but they are fully encapsulated in glass with no accessible " live" parts. I think, in spite of the outlay, I'm probably in pocket now due to the reliability ( and maybe reduced running costs)
