Silver defeats Sonic during their first meeting
>This is bad! They're forcing Silver on us! They're artificially making him win! He's stealing Sonic's spotlight by winning!
Silver gets defeated by Shadow later
>This is bad! Silver lost! He looks pathetic! Hahahahaha! Sonic Team wants us to like this character even though he lost?!?

I think people just want excuses to complain about the character/the game overall, well beyond what are legitmate complaints.
