Would you like to see True-Name Nemesis gone?

That's a leap of logic there. I'm saying convincing people why something is unfun is not practical. Banning a card because people feel it is unfun is quite doable, and has been apparently done in the past (based on the Sphere example).

Again, if you read the quoted text from Forsythe, he makes no mention of fun for Trinisphere's restriction in Vintage. The quoted text says it's "ridiculous", not unfun. As others have stated, the reason Trinisphere is ridiculously powerful in Vintage is because you have decks that can play 5 Black Lotuses and easily generate 3+ mana on T1 in a format that's dominated by 0 and 1 drops.

I don't think it's a far stretch to ask someone to justify to me their reasons for wanting to ban someone. If someone says a card is oppressing the format, I'll ask them to give me numbers to prove it. If someone says something is too powerful, I'll ask them to show me. If someone says it's "unfun", I'll say convince me why it's to such a degree that it requires a banning, especially over other generally accepted more "unfun" cards.

TNN doesn't do combat. It's a clock and a planeswalker assassination device. Could as well read "{T}: TNN deals damage equal to it's power to target player or Planeswalker). Play this ability only as a sorcery." and not much would be different. It doesn't swing in the red zone as far as most cards are concerned.

It's a 7 turn clock and why do we care that it can beat up Planeswalkers?

For Umezawa's Jitte, the card that most people agree is what makes TNN most powerful, it dealing combat damage most certainly matters.

It's a combat creature because it does only what every creature does - it only attacks or it blocks (of course, it does them both very well), ie combat.
