I'll try (I've only skimmed over the thread)

* Problematic with git's approach of addressing and tracking
  *content* (because the same file-content, identified by its SHA-1
  can be present in many different commits. A commit points to a file's
  content, but given a file-content, there can be any number of commits
  associated with it)

* It can break diffs (if the keyword line is part of the context and
  and the keywords are different (e.g., due to different branches))

* performance. Keyword expansion is expensive

* Linus Torvalds hates them

I seems that this mail covers most of the arguments (it's kinda longish)

Another argument is, that if keywords are desired, they should be added
when a file is exported from revision control (so that it's in the tarball)
