Bitcoin - Different systems (Bitcoin vs SegWit vs Lightning)

What are the differences between Bitcoin system, SegWit system and Lightning system and which one is true P2P, decentralised and which one is real Bitcoin system?

Which system should be called Bitcoin?

Please note that coin of every system is called by the system name, and note that Bitcoin coin name has been hi-jacked by Core & Blockstream as they count on exploiting lack of higher knowledge of users and the users not knowing how system works. Most users know the brand name only, as this is how mentality of consumers works, and Core & Blockstream count on this to trick you thinking you hold Bitcoin but you are not.

Answer is inside...

To all the Core advocates: You can bite me... I will keep calling you out
To all the Core shills: Stop being a moron and allow these liars to brainwash you. Temporal price of the coin is not determining factor of what Bitcoin is... THE WORKING PRINCIPLES is that what determines this.
