No, not usually, that's more like "part time job" or "side hustle." Just like nobody (hopefully) will say driving for Uber is passive. People often don't know what "passive" means, this question gets posted here a lot and most of the responses are not at all passive. A lot of people mean passive = non-wage income, not so. If it requires ongoing time and effort to make money, its not passive.
There's some grey/in between area though, real estate can be passive (1 unit with long term tenants) or a full time job (multiple properties, distressed properties in need of significant repairs, or something like AirBnB - unless you've got employees doing all the work). Same with stuff like writing, if the effort is already done and you just sit back and collect ad revenue or referrals, that's passive. If you're actively writing blog posts regularly, its not passive.
As far as the FBA case, if you've hired someone to do all the finding deals, packing and shipping, it is pretty much passive; if you've got a white label product and you've set up your suppliers to ship regular shipments from China direct to Amazon's warehouse, its probably pretty passive at that point.
Realistically, very few things are totally passive. Even index funds, probably most people's idea of totally passive, still take work -- taxes, reading statements, etc. For most people, I think passive is reasonably defined as less than a 2-3 hours a week. I probably spend that amount of time looking at my portfolio.
Selling on Amazon or eBay is surprisingly streamlined. Exceptions occur, but they're pretty easy to take care of if you budget them into your margins and don't try to jerk buyers around.
I sold a few hundred dollars a week on eBay and a "problem order" comes up once a week at most. Usually, it's just a full refund or a new shipment.
Last time I read about passive income here on HN it was mostly non-passive side hustles being shown.
Or stuff like ad revenue from apps or sales of books. Maybe passive now, but probably took quite some effort getting to there. It may be passive if the long tail is much bigger than the initial investment, but for most people I guess it's not.
Passive tends to mean earning money on rents from capital instead of your time/labor. The grey area is brokerage and arbitrage where you are earning money from risk.
