Rob - we're sharing our ideas freely here, on the internet. We are not the only group project that has produced scripts based on the Silmarillion and then shared them online. If someone adopts one of the ideas from Silm Film as part of their own personal 'fanon' of the Silmarillion, that's fine. As you say, it's not like you're running off to sell your script! Generally speaking, there's a lot of cross-pollination in the fanfic community, and a simple acknowledgement of another's work is enough to justify borrowing ideas from it. Copying or reposting someone else's work without permission is a different matter, but of course that isn't at issue here.
If you'd prefer to keep the work separate to avoid crossing the streams, that's fine. I just wanted you to know that no one here is worried about you 'lifting' anything from this project! If you're inspired by it, great, but no harm done.
If someone at Amazon 'lifted' something from our work, used it in their show, and did not acknowledge or pay for it...that would be an issue. But that obviously won't happen, because they know not to go looking, and it's not like we're e-mailing them copies of our work unsolicited, either!
Use of "ye" in the current draft of Episode 1:
Námo's dialogue: 5 occurrences
Finrod's dialogue: once (to the dwarves, as part of his 'diplomatic' conversation)
Sauron's dialogue: once (final line)
I also forgot to use -eth when Námo was speaking, so I have added one instance of that in as well.
