Note the disclaimer though. If the TOB goes bad completely it is beyond the scope of "noisy" and they could deny any other related work.

Mine started with a screeching sound on a cold morning when lightly pressing the clutch. Presing farther on the pedal loaded it up enough for the sound to go away. Releasing it again and then lightly pressing would produce the screech again. But after driving for a few minutes it would heat up enough to clear up. It was obvious it was the TOB so I tackled it that weekend. The clutch pedal felt much better after replacing it but this is the case after almost any clutch service where you re-grease everything. The improved feel is probably more the grease than the TOB.

What did the quill look like. Was it all scored?

Nope. I think I got it before it got that bad.

You could be correct. In 40 years and 20 or so MTs I have only had to replace one clutch so have never experienced stock back to stock. Any other replacements I did I was changing the whole works to performance equipment so I expected the changes. This change was more significant that I would attribute to just new lube though. I could also be second guessing myself at this point and the change wasn't as big as it seems.

Well looking at your photos I suspect a lot of your improvement was from the TOB actually sliding freely again. Mine was really fine other than not spinning well. I'm sure it was building up heat and at some point it would have melted like yours. I guess I lucked out and got the warning signs unlike with yours.

I had the warning signs. I foolishly waited to long to take care of it. Was my own fault it got that bad.

Been doing some research, I think the lack of proper lubrication to the TOB (courtesy of Toyota) and the fact that there is no f-ing clutch fork return spring to keep the bearing from moving around on its own makes the perfect storm for this issue. Thoughts?

Think it is plain and simple bad lube in the originals. The new one has no visible changes. The bearing isn't floating around in there it is pushed back by the clutch springs. There is no need for a clutch fork return spring.
The design of the TOB is not any different from TOBs reaching back through all makes even into the 1930s.
