I am entirely convinced that the original Wojak image was generated based off of extensive research conducted during MKUltra or other similar experiment programs by a three letter agency.
Obviously I don't have any actual evidence of this, but at this point it is the sole explanation that makes any sense at all with all the options that have been exhausted. I don't believe for a second that somephono in Poland could have designed this in the late 2000s just based off of his imagination. This was a psyop conducted by the United States that was possibly in the works since the realization of how the internet would be used to spread mind viruses to influence generations, and was produced just in time to realize it's potential. Just think of how much GDP was generated by the existence of the Wojak image and the giga-tsunami waves that it created in internet culture and the collective consciousness of an entire generation, not to mention the spiritual influence it inevitably had.
How else can you explain there being literally zero actual leads for the origins of the Wojak image, despite it's undeniably legendary status and being burned into the minds of hundreds of millions. Even if it was created just as a joke or something that just happened to become a meme due to the magic of the internet, you would imagine the creator would have made themselves known at some point or at least made follow ups, given how highly they would be regarded and probably have tons of lucrative work opportunities thrown their way
By process of elimination, I don't see many other possibilities for the origins of the Wojak image at all other than it being one of the core components of an elaborate CIA psyop.
