Sure, airlines can have whatever policies, but while not adhering to them might get you into trouble with the airline, it’s not a legal issue. The TSA doesn’t get powers from that to do anything that they weren’t allowed to do otherwise.
Now, they might lie to you to get you to give them more than they’re entitled to, but that’s a different issue.
You’re allowed to have devices with lithium batteries in checked bags.
When portable electronic devices powered by lithium batteries are in checked baggage, they must be completely powered off and protected to prevent unintentional activation or damage. Electronic devices capable of generating extreme heat, heating elements must be isolated which could cause a fire if activated, by removal of the heating element, battery or other components.
It’s a valid question if you live in a state that will only accept forms of ID which cost money to vote. I don’t know if that’s really the case anywhere, but if it were it could presumably be the subject of a lawsuit.
With the current SC, I expect that they’d find some bogus rationale why it didn’t count, but under a law respecting court, it’d be reasonable to require such states to provide suitable IDs at no cost.
I don’t think that it’s like a patent where the holder has to defend it; Oracle can decide to go after a license violation if they want to.
