ELI5: Why is "Ye" the only word we ever see with Y replacing the "thorn" character instead of th?

I understand the history behind how the thorn ( **Þ** ) character was replaced with Y in printing presses, which is why you saw signs like "Ye Olde Pub" instead of "The Olde Pub". Yet almost every word that used to have thorn in it now uses "th". The only usage that remains seems to be the word "Ye".

For instance, there is no "Yat Olde Pub" instead of "That Olde Pub". "Yis Old House" instead of "This Old House", or "Tom Yumb" instead of "Tom Thumb".

Why is it only "Ye"?

Part of the reason is confusion.  Ye (not to be confused with Þe) also exists/existed in English (currently depending on different dialects of English).  It also appears in older texts such as, "Ye of little faith," which in most English dialects would be translated as, "You all of little faith."

So people have confused Ye and Ye (Þe) as being the same word and think "Ye Olde Pub" is actually "You Old Pub" and think it's just some old fashioned use of Ye (again, not Þe).

I hope that was clear as mud.
