Because UEFI is designed to prevent hardware being booted unless it is
into an unmodified and signed OS version
You are confusing UEFI, SecureBoot[TM], and Microsoft requirements
concerning implementations of certain options.
I have booted unsigned operating systems plenty of times on a UEFI system.
and this hardware lock can be set up so it cannot be
turned off
That would refer to a particular implementation of SecureBoot, which is an
optional part of UEFI. Not every system with UEFI necessarily supports
UEFI, most which do allow you to disable.
For intel devices microsoft does not require UEFI to
be set so it
can't be turned off, for non-intel tablets it does. So Linux is
locked out of any such devices.
So don't buy ARM tables with Windows-RT on them.
and be very cautious of UEFI on any device since it
means you no longer
have control of hardware you thought you had bought and now own.
Not true at all. UEFI is just a specification for a boot environment. It
has a lot of cool features and is a lot more flexible than legacy BIOS.
If you are concerned that the secure boot feature might be locked down,
just make sure to ask whether secure boot can be disabled and how key
management is handled if you are considering buying a device with UEFI.

who are still producing board that don't have UEFI on them. Just because
"Microsoft" wants to control everyone doesn't mean the market will allow
that to happen. You can bet the Chinese and several other countries
(BRICS) are thinking twice about allowing UEFI to be placed on all their
citizens computers.

This is at best unproven and at worst willfully false.
UEFI does not represent a way to do either of these things. If it could do
that, then so could your existing BIOS.
There is little point in denying that UEFI plays into the interests of
Microsoft and large content providers, but that is very different from you
have claimed here.

Like the backdoor that doesn't exist on every cellphone? Or the use of
social networks to fulfil the CIA's promise project agenda. Or that
arcfour has not been compromised.
Anyone can choose to believe that UEFI does not have a seriously sinister
objective if they want. It's supposed to be a free world after all. When
they nuke North Korea some people will probably want to believe it was
because the North Korean's deserved it. We are free to believe whatever we
want to believe. Some people believe in god, some believe in fairies, some
believe in aliens. Well, you get the point ;-)

a backdoor is totally possible with the current BIOS architecture!
UEFI is about something different. If such backdoors exist now, they will
exist after UEFI (with the proviso that they may be more difficult to
hijack in a UEFI system)

What a perfect pile of nonsense.
Cell phones, and cell phone systems, are by law required not to provide
any features that can't be defeated by law enforcement. That is not a
backdoor, it's a documented feature you can or not be aware of.
Social media just expose the data that users want to be exposed. If you
care about your privacy, don't use them. You can't blame anyone for using
data that is publicly available.
The AC4 encryption algorithm has some documented weaknesses. They have
been known for at least 15 years by now. They are also relatively easy
to circumvent. And if you don't trust it, there are lots of much better
alternatives.
Regarding North Korea, it's a repressive police state with a political
regime that only serves its own interests. May I suggest you relocate
there if you like it so much ? At least then we'd be spared the sort of
nonsense you like to spread - you'd end up in some re-education camp
before you know it.

Speaking about North Korea: Shin Dong-Hyuk, which is the only known
person who has managed to escape from a a north Korean total-control
zone grade internment camp alive comes to the place where I work

I guess that will be a speech I never forget.

If this part were 100% correct, the problem would be much less. Other people
put data about you online. Including pictures and then tag them. They put
family relationships up even if you do not. It is not all something in your
personal control.
all the best,

I've got a special on tin foil hats at the moment.
