If you are a lawyer, you need to say "this is not legal advice".
IIRC, in the US, if you're a lawyer and someone "reasonably" believes you're giving them actual legal council, regardless of your intent, I'm pretty sure you're culpable (for lack of a better word).
Far as I can tell, it's not so much that you're actually culpable. But someone can sue you for it, and it won't be immediately thrown out, which means you may need an expensive and time-consuming defense. You'd probably win in the end, but what a pain in the ass.
It's 2022 and people still don't know that on the internet nobody knows you're a dog. These disclaimers always make me chuckle. I bet the amount of people successfully sued for giving advice on the internet is zero.
Possibly. It's pretty ridiculous what some courts/prosecutors consider "practicing law without a license".
For example, I was told by a judge that just if I help my wife fill out an appeal form, or if a real estate agent explains about a sale contract, that could be considered practicing law without a license. Frankly, that judge seemed like he was either an idiot or corrupt/biased based on some other stuff he did too.
He replaced a few components such as the CPU but we have seen Linux booted on a hard disc. Not from a hard disc but on the controller itself on the hard disc.
ESP8266 and ESP32 and the like are pretty tiny and have wifi and BT and a shedload of GPIOs and whatnot available. At £2 or less retail a pop! A "monster" system involving a Pi Zero costs about £5 retail.
My toaster is clockwork based or me and a long fork and a open hearth. My fridge/freezer on the other hand has a wifi link. It is on the SEWER VLAN which is for those devices that scare me somewhat and has a rather limited view of the world.
Hell, I bet the number of people who have even had a lawsuit successfully filed for advice on the Internet is very very small. A potential plaintiff would need contact info, for starters...
