at the office we have the ones you have to push down--and hold for the water to run. i've encountered them elsewhere and you get 10-20 seconds before the water shuts off... ours doesn't. by the time you get your hand down to the water, it's shut off.

i've seen two of these things around here. they've both been on the flatbed of a local towing service.
ad-skip to present day. encryption and drm is being introduced into the new atsc 3.0 broadcast standard, and some stations are already using it.
i bought a few smr drives, knowing they were smr. they were cheaper, a lot cheaper than the same amount of space in cmr. used only for static media storage, so that's not a big deal, really., but holy hell was it slow getting stuff on them initially.
i have a few self-powered externals that are also smr (quite common with those as they use 2.5in notebook hdd). when those things have to start shuffling bits around and rewriting tracks, sustained write speeds fall well under what even usb2 can send.
i bought a big external hdd recently on impulse... a clearance sale. it was really, really cheap. with the thinking that i could 'shuck' it because i'm short on space in a couple storage systems. i checked. i can, but i haven't. hell, i haven't even used it yet other than to run a full smart diag on it, followed by a full format and a read/write verify. took days. then i put it back in the box and have basically forgotten about it until now.
you have to be careful on what models you buy. some have usb built onto the controller board (no internal sata) or other things (e.g. encryption chip, weird power) that make it more difficult or even impossible to use the internal drive in an environment other than the enclosure it ships in.
ting hasn't been the same since dish bought it from tucows.
patents is what you're thinking of. and all (afaik) of them relating to mp3 format have expired.
verizon did the same thing awhile ago, and it was more than five bucks a month.
was still cheaper for us to keep the old plan than to switch to a new "unlimited" one, though.
usb nvme adapters are not expensive and it likely won't be the only time you need it. they are a handy accessory to have on hand if you have nvme storage.
don't mess around with imaging to a file on the zfs, then restoring it. simply clone nvme -> nvme using a usb nvme adapter then replace the internal with the clone.
it'll be covered on screen 73 of the 'agreement' required to use the device.
