alt Hacker NewsPPPoE is pretty much only used for DSL in the US. I'm not sure about elsewhere.
Xfinity and AT&T Fiber do /not/ use PPPoE. Xfinity is built on DOCSIS, and AT&T Fiber is built on XGSPON. This means neither one relies on PPPoE at the data link layer. XGSPON uses XGEM/XGTC at data link layer, DOCSIS uses MAC (same data link protocol as Ethernet).
This article is making a bunch of assertions which are just patently false. PPPoE is basically old hat at this point. It's extremely high overhead anyway, so is only used for DSL because DSL is an old approach.

Some of AT&T's fiber acquisitions still use PPPoE including CenturyLink and Quantum's fiber offerings (acquired from Lumen).
Mind telling us which assertions are false? They make no claims about pppoe adoption other than that’s what their connection uses.
My fibre connection in the uk uses pppoe (2gbps)
VDSL2 is using PPPoE here in europe often. Havent seen it used on PON based internet connections though

I have 4Gbit symmetric fiber over PPPoE (+ a VLAN) in NL. It's quite common here in Europe. The Unifi Cloud Gateway Fiber, handles it well though (as mentioned in the article).
