Listing the changes is not necessary. Theyre well aware of the changes and know it’s what drives our desire to see the originals restored. Listing the changes might come off as degrading the SEs which is not the purpose of the message. For once I agree with Alderaan. Mentioning the SEs as less as we can, aside from maybe mentioning that we can respect that they are the canon versions and are how Mr. Lucas intends them to be, is probably a smart option. We just want the originals restored and released regardless of what release method they should choose to do so.
We could even take it a step further and show we’re also not prequel haters by pointing out that those movies aren’t available in their original forms either (at least TPM and AotC aren’t).
Including the words “the original and prequel trilogies” and “all versions” in the relevant parts of the longer letter would be just subtle enough.
