Hikvision appears to be destroying its customer's property.
See, Hikvision are just doing dumb stuff with firmware. For example, my old man has a 7616NI-SP nvr. When he got it the firmware needed updating (from the genuine channel in Aus). The local distributor gave him an update, he installed it. All good. This update is a custom firmware file Hik did for Aus. It's a 3.1.0 version, but compiled with tweaks over 18 months after the original multi-language 3.1.0 version. In fact the compile dates on that 3.1.0 line up with about 3.4 for the same NVR available on the net. Plenty of warnings not to update, and this is from the *official* Hik channel.
Hikvision have history of pushing out special builds for specific applications. I know of an airport that has about 400 Hik cameras in it (boy do they regret that, but that's another story and the muppet involved fell on his sword). All of those have customized builds that came from the Hik factory. Upgrading those cameras using standard firmware breaks shit. So it's not malice. It's crap software & QA practices. Cheap-arse "yeah we can fix that for you, hang on and i'll send you a firmware" without proper change management, and firmware workarounds for manufacturing balls ups (like oh we sent you 100 cameras that had the wrong model identifier in flash, but don't worry we'll give you an updated firmware for those. Guess what happens when someone updates them with official firmware?).
When you don't have adequate validation of upgrade files, shit will happen. It's not deliberate, it's laziness and ineptitude. Mix that in with cameras arriving from grey market channels with firmware that doesn't match the flash and workaround hacks and it is obvious what will happen.
Plenty of stories of people bricking motherboards over the years by flashing the wrong firmware, are you going to accuse the motherboard manufacturers of deliberately making it possible to brick those as well?
If people voted with their feet and stopped buying shit cameras, the problem would solve itself.
