In the Trivia section, it says he is "based off of" Tabi. If the definition of "based off of" is "literally the exact same as" in their eyes, then yes, this is "based off of" Tabi.

This is literally shitty Sonic OCs but instead of copying the shape and just giving it a shittier recolor, they just copy the entire damn thing!
