Like Spanish and Italian are the same thing.

Because they're both Latin.

First, they are not same thing. If they would be same thing, russians could speak or understand Ukrainian language (they can't).

Second - I don't have russian accent. I don't even speak russian. I could agree that it can be 'slavic accent' but why attribute it to russia, majority of which is non-slavic literally Asia?

Guess what - russsian developer. Who knew.
