I was loyal to Sony for Analogue electronics: clever, straightforward, mini hi-fi, Trinitron CRT tvs, a car radio/cassette player. All solid, reliable, high quality sound (& picture). Then came the first Sony Tv with teletext/viewdata/whatever it was called that week. I had to have 4 before I got one that worked. They argued all the time that there was nothing wrong.
Then the removal men dropped a 1 year old telly. It was 4 years before the insurers returned it, because of problems with Sony supplying parts.
I'd stopped believing in them long before the rootkit fiasco, although that was when I stopped buying anything, already annoyed by a lock-in policy that covered cameras, audio players, etc.
They made their name with good quality affordable well supported products, Once they had the name they dropped the other 3 things. And I dropped them.
