I don't disagree. But the problem starts way before that. The problem starts when manufacturers decide at the design stage to make something proprietary that could be done with a generic part. It's not exclusive to Autel, nor even to drones. It's been going on forever.
Remember typewriter ribbons? They were all basically the same: a ribbon of cloth or film with some sort of ink on them. Yet there were a bazillion different cartridges and packagings, most of them identical save for some notch, tab, or peculiar cartridge shape intended to prevent you from using any other than the one specifically designed for your machine.
Printer ink and toner cartridges are another example, except they're a bit more sophisticated. They contain chips, optical indicia, or other logic designed to prevent you from using third-party cartridges or refilling OEM ones.
And then there are phone batteries. Before I switched to iOS, I would watch teardown videos of the phones I was considering before buying one, specifically to learn how much of a bother replacing the batteries would be. The lengths to which some manufacturers will go to make that impossible is astonishing, to the point of a technician having to risk his or her life to use a heat gun to
melt the glue they use to guarantee that the original battery can never be removed.
They use methods bordering on intentional homicide to guarantee obsolescence. And yet people keep buying their phones.
As an aside, that also was a secondary reason why I switched to iPhone. Although Apple also takes actions to prevent the use of third-party batteries, they'll replace the battery in any iPhone with an OEM one, for a reasonable price, until the phones are obsolesced by other factors (for example, new RF bands). I had the battery in my granddaughter's iPhone 6 replaced at an Apple store for less than USD $50.00 while we shopped the rest of the mall.
There are only a handful of battery chemistries, with Li-Po being the most suitable for high-draw devices like drones. All of these batteries have standard, generic form factors that are chemically and electrically identical. Using anything other than a standard battery, and then removing that battery from the market, is planned obsolescence.
