Well I wouldn't be so categorical, I sold my atrociously crappy finished Honda Africa twin, rusting all around and having sh*t bearing, bad gearbox and more, was hardly the only guy, most 2016 models were crap.
I see some kawis looking awful nowadays, seems there's hardly Yamaha and maybe Suzuki still being quality.

So it's more of a mentality, we try to get away with it until people are too annoyed, all manufacturers are slowly going this way unfortunately.

My friends that put so much money on their beeemers, kind of snobbed up, it's so weird, but they already said they'll buy kawis next because it costs too damn much !

Yes, a local BM dealer (smaller & single-line) has recently closed -- fighting with the importer, reportedly, part of the problem. Many smaller. "mom & pop", dealers don't fit BMW's modern business profile -- modern large edifice alongside a big highway.
But, Triumph aren't doing so well in that regard - either. My selling dealer closed and 2 other dealers I could use have also closed.
Other brands seem to do better in terms of dealer longevity..?

With Beemers, I thought that was a "feature"..?

The biggest problem I see concerning BMW is the lack of dealers. I live near one of the largest metropolitan areas in the world and the nearest dealer is 30 miles away. That might seem for some as not very far but in my area there are dealers of all major marques much closer and more numerous. I've also noted that the personnel are very snobby.

There are many seat upholsterers, I used Digger seats & Tony Archer. They are not handy for you. The TOMCC folk down your way will know somebody local to you.
