Unethical business practices are Sony's forte.

So people are catching on the the negative PR spin which is taking the 78% figure entirely outbound context, which is precisely what you did in your OP. 

Who is actually guilty of the most egregious spin? The one who says "we sold the most out of anyone...on a Tuesday afternoon... in the third week of July...in 2014" (akin to what Sony did), or the one who says "they just falsely claimed to have sold more than anyone." (akin to what you and your quoted sources have done).

One is the truth in a very narrow and somewhat meaningless context to create a positive vibe. The other is a complete misrepresentation of the original PR, and made with malicious intent in order to manufacture a negative vibe.

If you want to criticise the PR do it on its own merits and in the proper context. Don't try to turn it into a lie by omitting important context and then say for "shame ye aevil Sony".

When people twist truth and try to present it as a lie it is usually because they are salty or angtsy about something they can't actually criticise. Which in this case was Sony announcing a whole lot of new content for PS4 (and PS3) which puts it on a very competitive footing with Wii U. Including the first appearance of the DQ franchise on PS since PS2(?), which for all of last gen was firmly in Nintendo's grasp.

This is PR 101 and yet, some people act so surprised... I currently like Sony the most out the three, but that doesn't mean that they do everything right or ethical. I do understand what Sony is trying to do: get the Japanese audience hyped for the PS4 (and I guess, the Vita, too) and build on that momentum.

If this was acknowledged by the OP then there would be no Op becausebthere would be nothing to see here. The issue is that Sony's truthful statement is being painted as a lie, or at best an outrageous misrepresentation. When at worst it's a cheeky misdirection.

This is a manufactured controversy because a few people are worried about all the games announced in that press conference. 

But the sales have been strong in Japan even before 2013 when it was just the PS3,
If we start the marketshares at the launch of the WiiU until today, we get the following:

WiiU 633377, 946047, 314468

All home consoles: 5,637,992

Marketshare:
Nintendo 43%
Sony 55%
Microsoft 2%

If you start as far back as the Wii, it's more or less the same but with the nintendo and sony values flipped, largely because by that point you're including two additional years of market presence of hardware that sony did not have (wii sold a year longer, wiiu sold a year longer).

So while picking the numbers for JUST 2014 does indeed give Sony a boost, it's not like not doing so would result in "worrying" numbers anyway.

The topic was about them lying about the numbers and that was disproven. Everything else you listed was filler just so you could say Nintendo is the obvious winner while Sony isn't doing well and you evens stated it as a fact.  You even had a go at calling out other users and wanting to ban them. How you don't see what you're doing is astounding. 

Not a spin at all, just a misinterpretation.

The Wii and PS3 both came out in Japan at the end of 2006.
