Electronics manufactures must from Saturday fit all devices sold in the EU with USB-C charger ports in a bid by the 27-nation bloc to reduce waste and cut costs for consumers, who will no longer have…
I believe USB A-to-A cables actually violate the USB spec and should not in fact ever exist. They definitely should not exist as a straight-through cable (although obviously they still do in reality) without any active electronics in the middle. Male A plugs are solely for connecting to a host device, and the entire purpose of the spectrum of B plugs in their various guises is specifically to make the other end of the cable that goes into the endpoint device different. The point is that you are not supposed to be able to directly connect two hosts together like that.
A straight through dumb A-to-A cable would connect the +5v pin from the host device directly to the +5v pin on the device on the other end of the cable. If you did this between two host devices (i.e. two computers) it is certainly possible that Bad Things would happen if the designers of both devices did not account for this type of stupidity. The only way one of these can be valid according to the spec is to omit the power pins entirely.
That said, I have a particular flashlight that came with exactly one of these naughty cables: A straight through male USB A-to-A cable with no smarts in it whatsoever. The flashlight charges via a USB-A port which is exceptionally bizarre, and I suspect the reason it does so is because it can also act as a power bank and the manufacturer was too cheap to include a type C or micro B or whatever port for input and a separate type A port for output. But now I’m stuck having to use the moronic cable it came with (which is also only like 14" long) without much hope of ever finding an alternative or replacement…
Speaking of illegal weird cables: I actually have a Y shaped cable, USB Type-A male to USB Type-A female with an extra red USB Type-A male to inject more power if the host can’t power the device otherwise.
I’ve used it once to attach an external HDD to an Android Phone with an OTG male micro-B to female A adapter. It worked but it was kind of stupid :-D

Those used to be common for stuff like external drives (HDD, DVD…)that needed more power than old USB ports could provide, so they used two
