Of course it's massively misleading, it's farming for updoots.
Further proving the (unpopular) point I made earlier today: https://news.ycombinator.com/item?id=47066456
Source: I own one of these iBooks and it most certainly can NOT connect to modern Wi-Fi, not out of the box. IIRC it cannot do WPA2, or required an update to do so, which was not available in the Tiger install media, so a chicken-or-egg scenario. Definitely will fail on a mixed WPA2/WPA3 network.
Assume it can connect to Wi-Fi, the TLS libraries are ancient and nothing will work. Including authenticating to iTunes, etc. Samba is ancient and will not connect to shares running SMB2 or newer. It also ignores than OS X versions newer than Tiger have broken App Stores and other things.
Wait till everyone finds out Apple served software updates in those days over plain HTTP which is why it "works"...
