Actually, no. There is quite a bit of work in Squeak that I have done 
that is clearly not owned by the mouse and where I have proof for it. 
Weak references is one of them, see for example:

http://isgwww.cs.uni-magdeburg.de/~raab/squeak/dev/Finalization/2.0/ObjectMemory-Finalization.st

This was released in May 98 (I can probably still find some email 
conversation that goes back into 97) and I started working at Disney in 
December '98 (finalization first appeared in 2.3 I think which was 
released late 98, too). And although I did some consulting work in mid 
to late '98 for Alan's group that code was long released by then. I did 
it on my own, in my spare time and I own the copyright to these 
modifications. (besides that particular code is stupid and should be 
replaced anyway; I now know much better and easier and more flexible 
ways to deal with finalization)
