I also think that brands are being attacked and devalued.
Look at all the ASKJKL type uppercase brands on amazon.
Meanwhile trusted/established brands are impossible to search for specifically.
And established brands are bought and sold to bad new owners. Pyrex was sold and doesn't make good (borosilicate) glass products anymore. Segway went to ninebot.
I'm sure there are lots of examples of this...
Many established brands now have official stores on Amazon. Like here's one for Bose (not an endorsement). Search takes you right there.

I don't think that Segway was ever considered trusted or established. It has always been kind of a goofy niche product used by guided tour groups and mall security.
