I'm quite familiar with that one.
The worst one was the pre Raspberry Pi 3 boards. The early ones used an on board Ethernet chip set that was slaved directly to the USB controller. It was USB 2.0 so it could negotiate 100, but really run much less than that.
Then, if you put in a keyboard, mouse, and a USB thumb drive the USB host would multiplex over them and your bandwidth for data transfer would drop precipitously.
I was so happy when they moved to a real Ethernet chip instead of a USB adapter. The new limitation became the microSD... Of course they also introduced the grounding reset issue on the USB port, but just don't plus or unplug anything and it'd be fine.
I don't feel this push for locking us out of control over our own systems under the cover of "protecting the children with age verification" is anything more than a continued effort to secure a DRM-based hardware system for the MSFT OS and media companies. This smells just like their pushes in the past to steal control over hardware through legal channels. It's the same war we've been fighting for 30 years now.
Read up on the Clipper Chip from the 90's. What's old is new again.
