I'm honestly a bit lost for words here. Babies aren't supposed to be mobile in a bassinet -- usually they're swaddled or wrapped up. If they're mobile then they're supposed to be in a crib.
A baby in a sleep sack in an unplugged snoo ("strapped down") is not wholly distinguishable from a baby swaddled in a soft-sided bassinet.
I'm not advocating for actually using it this way, nor for soft-sided bassinets, but... you compared the snoo to a swing. You are not making much sense to me.
I compared the build quality of the SNOO to the build quality of a cheap baby swing. If it helps to avoid confusion, one could compare it to something else cheaply made that isn't also a device for rocking babies back and forth.
