As for your reply about cell phone support, Apple just recently discontinued support for the iPhone 6 (everything newer still receives support), and Samsung just recently announced no further sorry for the Galaxy S6 & Galaxy Note 5 (again, everything newer still receives support). Typical "length of support" in the tech industry is a minimum of 3 years, with most providing 4-5 years, and some providing as much as 7 years (Microsoft & Apple, for example, both tend to fall into this last category).
For iPhone, the iphone 6 & 6Plus were "discontinued" officially Sep 7, 2017 as hardware sales, and no longer "supported" for new release of iOS beginnig with iOS13. But even still, it continues to be supported with repair service, screen & battery. Same with Samsung, they loose OS support eventually but continue to receive service or repair support by Manufacture til inventory dry then 3rd party Service & parts.
The iPhone 6 (and older) continues to function fine, still cellular operational and can obtain apps from the App store but is limited to iOS12. I have an iTouch that is capped at iOS 8 or something, and it continues to receive updated Apps. Have an iMac27, i7, 32MB, 3K screen, 4TB internal SSD (2 drives)... capped at High Sierra, continues to get updates and runs great... even better than the newer iMac limited to the i5 CPU (iMac Pro i7 & i9). Same with a field Macbook Pro15 & 17. All discontinued, all still serviceable, and all still able to obtain updates except newest OS. Don't require 4 / 5K screens to "edit" 4K footage.
The age of 5-7 yrs used to be business norm to cycle PC core wk-staions and servers, that later become a ridiculous 3 yrs on many hardware: $100k Switches, $200k SSD NAS, downward to including Wk-Staions. Dropping their OS or Technical support doesn't mean product is unreliable, just means no longer profitable.
They'll continue to operate, able to update some programs and serve well beyound offical support. The Y2K scare was based on OS & DB designs being replaced long before 2000, but companies at that time didn't cycle hardware just because an arbitrary number of years. Many mainframes & mini's continue to operate that were expected to be replaced years ago... several 3rd party companies have a healthy income providing components for discontinued hardware.
The WinXP died what... 3-4 yrs ago? Most anti-virus, malware tools will continue to install and update on WinXP. They still run the Non-cloud based "pay once" OS, and perpetual licensing programs... they don't support the yearly renewal products with a never ending cost. Wanna guess what drove the EOL factor the most on the above hardware, it wasn't 8 to 32 to 64 bit OS... it's called profit!
How many still run Photoshop CS6 or the "Real" Lightroom classic 6.xx? Zero cost, still runs great, and the Raw programs are still upgradable. I do... zero cost and every new Photography SW program: Lumina, OnOne, Topaz, etc continue to prompt and install plugins.
So it's not simply a Manufactured End of life, discontinued issue... more of the ability to continue to repair, operate, update and obtain new components or apps.
That's been a problem with Yuneec on some products barely out the gate and several just a few years old. Development stops internally and not shared or encouraged externally. Someone above mentioned Inspire or Phantom... you can still get components, even 3rd Party sensors, software, etc for these easily... the Inspire 1 is the oldest Professional "Consumer sold" craft and can mount the newest Ag Multispectral camera, 3rd Party Specialty sensors and run the latest Autonomous programs, and still mount MFT 4K camera with newly released 3rd party lenses... dispite being Officially discontinued a few years ago.
That's the difference: continuation and availability of service life reciprocate into endurance and support by consumers... and professionals. Again, something Yuneec needs to adapt and prove to consumers.
Lastly, the new Lica Camera... what's the major selling point? Not adjustable Aperture, high EVO, Interchagable Lens, Mechanical Zoom Lens, larger MFT sensor... so a mild improvement "maybe" to existing on H Plus?
