Just because ultrasonics are inaudible doesn't necessarily mean they're harmless. Energy deposited into those little hairs in your cochlea is still energy. What does the research say about the impact of ultrasonics on hearing? I wouldn't be surprised if they're the same as any kind of sound, decibel per decibel. (They're easier to block out, being at a higher frequency.)

Whoa, wait a sec there with your example. How would a reasonable person not want to be an organ donor??
Religious reasons, family not wanting that to happen, etc.
In short, only a few religions have anything to say against being a donor at death, and a few have something against being a recipient from a dead person.
If you think your religion might affect your decision to be a donor, check with a trusted authority figure and make sure.

There is a theory that organ donors get worse medical attention and have higher mortality rates in hospitals. From what I've seen it doesn't hold up well against the evidence, but it's still within the bounds of what I'd call "reasonable disagreement".
That doesn't sound reasonable at all. That theory hinges on the idea that doctors would prioritize getting organs over actually saving people's lives, which would be a truly horrific violation of the hippocratic oath.
Doctor's don't need to consciously change their behavior for there to be a difference in care. It's just that incentives are like really awesomely powerful things.
> all the time, even while they’re running in the background This is FUD. iOS does not give an app this ability without it being obvious (a banner across the top of the screen).
Apparently 9 in 10 smartphones today are Android and that lets you do whatever you want in the background.
I'm working on an app that passively picks up ultrasonic tones generated by SilverPush and sends out garbled data. The biggest issue with blanket interference across the entire ultrasonic band is that there are some legitimate uses that don't involve cross-device tracking. That's why we need to address this issue by selectively interfering with only known tracking schemes.
Can you elaborate on which legitimate uses you had in mind?

Do you have details on the encoding? I'm a bit suspicious of it being actually ultrasonic (device microphones often filter at 20khz or below) - seems more likely it would be audible spectrum noise with a ton of FEC.
Some preliminary work was done last year to reverse SilverPush[1], but my group and I are planning to take it further.

Where can we follow this project?

Here's some research: https://www.ncbi.nlm.nih.gov/pubmed/18555116 In short, only a few religions have anything to say against being a donor at death, and a few have something against being a recipient from a dead person.

A person's choice is probably always valid regardless of what it is, it's their body at the end of the day. In the normative sense I think everyone should donate their organs, but I'm not sure it can be reasonably codified.

Poor me, I can hear the ultrasonics generated to repel dogs and cats...
Yeah, apparently you're supposed to lose that ability in your mid-20's, but I still hear them loud and clear at 28...
