Such actions are part of the private sphere, which the state has absolutely no business policing, unless e.g. you commit some violent crime or are diagnosed with a severe mental illness.
The state's policing of what we are allowed to read is a modern day witch hunt.
Such gatekeeping almost always ends up preventing new innovative entrants from coming in. It protects those who have the certification from competition. Thus leading to stagnation in the industry.

Large corporations cater to the masses, so they follow these fashionable dumbing down trends in order to satisfy marketing/branding goals and maximize revenue. If it looks "trendy" then it will generate more sales, revenue, etc. And open source software ends up copying it unthinkingly.
Registers 0x7d10 (sequence number) and 0x7d38 (TLP data) allow you to send custom PCIe TLPs, which let you do the configuration space writes required to get the other card to talk to it. https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&d... (see page 383)
It's quite suprising to see one NIC blinking the LEDs of another, by writing to its registers over the point-to-point PCIe link (I used twisted-pair wire-wrap wire to connect them together).
Here's the code to do it, you run it on the MIPS processor: https://pastebin.com/ZJdaUpRZ
This is enough to load custom firmware on a GPU, and get the two talking together, with network access, by the way!
Also the Intel i210 NIC can do this as well, it has an ARC Tangent-A4 processor in the management engine. Same for the i225, but I believe that one has secure boot to prevent unauthorized firmware from running.
Some schools ban phones completely. And the school is not responsible if the children can't call 911 if there's some emergency for example.
And some buildings are constructed of materials which will obstruct the mobile signal as well. Nobody is held responsible for that when they can't call 911.
And I believe it's perfectly legal for me to use radio-blocking paint on the walls of my own house, that might obstruct the signals for the neighbours as well, if I'm hypothetically in a weak signal area. In that case the mobile operator has no right to force their signals through my home, it's within my right to block it as long as I don't use any form of illegal jamming.
By the way, Some of the Broadcom chips have an integrated 8051, with on-chip ROM firmware. There are leaked datasheets floating around somewhere as well. If someone has the time to dump the on-chip ROM, it would be interesting to see what's in there. Note, some of the pins marked NC in the datasheet are in fact the 8051 UART TX/RX lines.

The removal process is quite spectacular, you can see apt delete hundreds of interrelated dependencies, one after another. So satisfying to see it all go.
Voice recorders and storage are very cheap nowadays, keep them on you, running at all times if you ever find yourself in any similar circumstances. That way, it's no longer of "he said, she said", and it's clear who the problem is.
Of course assuming this is legal to do so where you live.
If they want to ban drugs in general, then they should prosecute those supplying it and those producing it for sale. Not private individuals consuming it in their own homes, and causing absolutely no harm to anyone. And those who are consuming it in public while presenting a danger to others, that can be made illegal. Failing that, they can outright ban public consumption.
In 100-200 years time from now people will be talking about this, just as we look back to barbaric times in the past now.
The laws regarding child pornography possession are "strict liability" in many jurisdictions. So these laws prevent entirely legitimate activities from being carried out, because of the fear of being persecuted (it has parallels to the Salem Witch Trials).
