I quit facebook (as a user, never worked for them). I may drop Netflix. I've been mad at apple ever since I bought a powerbook that crapped out within a year and a few months, just outside the warranty (I never bought the extended, it was Mac, they never break), and was told I'd have to pay $350 to fix it (I didn't damage it in any way, it was just a turkey of a product), but I'm still using an iPhone. Amazon prime remains immensely popular in my household both for movies and tv shows and ordering gifts, books and groceries, and while I'd like to to use it less, I don't see that happening. I use Firefox and duckduckgo as much as I can, but still use gmail, google docs, search, and google cloudplatform and AI notebooks - the latter extensively.
No idea if my own personal preferences or needs have anything to do with overall appeal or decline.
I worked for Sun Microsystems once, late 90s-2001. A lot of people figured the dot com thing would take a tumble, but felt good about Sun's prospects (as workers and as an investment) because Sun made real tangible things, servers and workstations.
Amazon, at the time, was a bookstore with a "dot com" tacked on to the end.
Apple hadn't yet released OS X and was often accused of coasting on good looks and being pretty.
There was no facebook and wouldn't be for a few more years... there was "the globe", friendster, a few of those. When I was at Sun, I sat in an office that is now facebook.
Google was around, though a lot of people were saying search was no longer a differentiator, and that the important thing for a search engine was to become a portal and be "sticky", and be a bit more like a content provider, entertainment hub, and so forth.
The people who thought Sun was a good bet made perfect sense - in retrospect, they had it wrong, and some people accurately pointed this out at the time... but you could make a reasonable case for Sun.
So... just sayin'
