The above statement was for OpenBSD and it's lack of browsers on PowerPC. I haven't messed with OpenBSD in awhile, but what is available is pretty up to date. They just aren't full featured or very capable outside of basic browsing.
Linux on the other hand is much better off. It has current webkit based browsers like eolie and epiphany (gnome web), pale moon, sealion etc for 32bit. PPC64 (G5) also has current firefox, but it had some endianess color issues last i used it. You'll be able to access most of the web, but unless you're on an intel or arm machine running chrome (or its variants) don't expect every site to work. Without widevine for PPC there is no way to use sites like netflix, hulu, spotify, zoom, etc etc.
TenFourFox / InterWebPPC / ArcticFoxPPC all play youtube fine, but you need a G5 to get 360p/480p/720p playback. A G3 just doesn't have the muscle to do it these days. That's where apps like PPCMC come in handy.
