Oh yes, the port that HTML passes through

I don't see the problem. Type-C ports can replace all those ports. If you want more ports, buy a dock.

Where is the removable battery? Did ANY Apple laptops have that?

To be fair, USB-C, especially with Thunderbolt, is much more universal. There are adapters for pretty much every "legacy" port out there so if you really need FireWire you can have it, but it's clear why FireWire isn't built into the laptop itself anymore.

The top MacBook Pro is also the 2016+ pre Apple Silicon chassis (that was also used with M chips, but sort of as a leftover), while the newer MacBook Pro chassis at least brought back HDMI and an SD card reader (and MagSafe as a dedicated charging port, although USB-C still works fine for that).

Considering modern "docking" solutions only need a single USB-C/Thunderbolt cable for everything, these additional ports only matter when on the go. HDMI comes in handy for presentations for example.

I'd love to see at least a single USB-A port on the MacBook Pro, but that's likely never coming back. USB-C to A adapters exist though, so it's not a huge deal. Ethernet can be handy as well, but most use cases for that are docked anyway.

I like the Framework concept the most, also "only" 4 ports (on the 13" at least, plus a built-in combo jack), but using adapter cards you can configure it to whatever you need at that point in time and the cards slide into the chassis instead of sticking out like dongles would. I usually go for one USB-C/Thunderbolt on either side (so charging works on either side), a single USB-A and video out in the form of DisplayPort or HDMI. Sometimes I swap the video out (that also works via USB-C obviously) for Ethernet, even though the Ethernet card sticks out. For a (retro) LAN party, I used 1 USB-C, USB-A (with a 4-port hub for wired peripherals), DisplayPort and Ethernet.

The new (not that new anymore) macbook PROs do have separate DC input, HDMI, SD card slot and HDMI. And to be honest, for an average computer user those ports are pretty useless, however if you do need them it comes at a rather steep premium.
