>>40208137Porygon still causes a lot of controversy even to this day, even if Pikachu was the actual cause of the incident. The media thinks that the seizure happened in the Porygon episode, so Porygon is to blame. The virtual reality setting and the use of VR rockets brought about the flashing light scenario, a setting that would have been impossible without Porygon.
Still, Game Freak and The Pokemon Company have some role in the anime, and the anime as a marketing and licensing tool is extremely important to them, so Porygon is probably on their minds.
