Honestly you often don’t even have a choice they don’t even give you a modem that does ppoe pass through or bridge mode.

Right, because 99% of their customer base does not care. TikTok and YouTube work without "bridge mode," as does Fortnight / Roblox / Minecraft. Any random Comcast or AT&T Fiber subscriber on the street won't be able to tell you what "bridge mode" does.
