Unfortunately continuing to burn money with no hope of recovery is not a popular strategy among judges and creditor's lawyers. Customers will either get refunds or join the back of the creditor line.
They wouldn't have to set anything. The transponder on almost any modern plane defaults to automatically on, either immediately or at takeoff. With Mode C (reporting altitude) or S (& reporting more) and squawking 1200 (VFR).
These have been standard equipment (that you buy, or the school loans out) in middle-class US high school math since the 90's (and gone basically unchanged since then). The math books even have content tailored to particular models so that you'll have to buy them instead of alternatives from other vendors.
What you are likely thinking of is the "selective availability" system, which intentionally provided slightly inaccurate data to civilian clients, while military receivers could decrypt the most accurate info. But this has not been used for many years now.
Other than that, GPS is a one-way system, it does not know you exist, how fast your receiver is moving or "give" different information to one client vs another.
Even if it did, this is essentially a toy and moving slower and lower than a general aviation plane.
It uses accelerometers and other sensors because they can be sampled and integrated hundreds of times a second. The $5 gps module is 9600 baud serial and provides one update/second (or maybe 5/sec depending on which part number you pick).
This is not even close to the worst ideas Apple ever had, even if you're only talking about mice.
The original USB mouse (for the first iMac) was round, so you couldn't orient it in your hand without looking at it constantly.
And it came with a very short cord (because there was a port on the right side of the keyboard to plug it into). But then the laptops got updated with USB ports and they were only on the LEFT side of the case.
For at least a year or two you could not buy an Apple mouse for your Apple PowerBook and use it in your right hand, because the cord was too short to go around the case.
Eventually they shipped a "Pro" mouse with revolutionary elongated shape and longer cord. (...and optical tracking, and what looked like zero buttons, which were pretty neat)
If you don't go often enough you definitely won't make the same progress per session. You'll spend most of each session trying to remaster what you lost from the last one.
For powered flying, one a week is already on the low end... most instructors would recommend 2-3x/week.
Flying skills are very perishable, especially when first learning. This is why there are several different rules about recency of experience before you can do things like carry passengers, recurrent training requirements, etc.
Testing on the ground and problems with what most people would call the payload (Apollo 1 & 13), sure.
But we're comparing to SpaceX launches. Plenty of Raptor engines have blown up on the ground too.
There were 13 Saturn V's launched and all of them basically performed their mission (Apollo 6 being a bit of an exception) with 0 rapid unplanned disassemblies...
Personally I'd rather buy one from IKEA and use the change left over from $12k to buy.. a used truck to drive the sofa home in.. but apparently there's a market.
You can certainly go much higher for smaller companies producing actual custom stuff, using exotic materials, for a giant sectional instead of a single sofa, etc.
That is exactly how npm works. Except instead of one at least somewhat-aligned group of maintainers of a Linux distro trying to keep things under control, you have a much larger set of packages individually maintained (or abandoned) by totally independent people.
So practically nothing will ever exactly match, which leaves you right back at many slightly-different copies of hundreds or thousands of dependencies.
I don't know of any particular popular concrete instance, but why is it hard to believe? It's trivial to implement and would be brought to you by the same people who think serving ads for NXDOMAIN is a good idea.
It's possible your ISP is intercepting all traffic for port 53 and sending it to their own nameservers (which do send client subset) instead of you actually taking to cloudflare's 1.1.1.1 at all.
