I think all of us in 2019 have a fairly standard consensus understanding of what technology means in the context of this conversation and it would not be good to hijack that to mean anything you want it to mean.
The actual definition[1][2][3] of technology is applied science and knowledge for practical means. Narrowing the scope to fit arbitrary companies seems like the real stretch to me.

Amazon is retail, like Walmart has been. Netflix is media production and distribution, like Fox has been. Both have figured out new business models but that doesn't change the business that they're in.
They leverage some damn impressive technology, but their business is about delivering media for end user consumption, much like any of the TV companies during most of the 20th century, for example.
Doing anything at scale pretty much turns you into a tech company these days.
