By reverting back edits we risk escalating more censorship suggestions (from legal team of SE) and their consequent implementation. I say "escalating" because everything is a possibility now after this new policy. By everything, I mean reducing or even erasing from public view access to information which could be deemed supportive of the greater cause many of the community members are now deeply invested in.
If SE disagrees, then they can lock the posts while the content dispute is settled.
There is to nothing to settle for the staff as far as the content is involved. They made it a matter of policy under which there is no scope for discussion or negotiation.
As to what to do to add clarity back to the question, my following suggestion is not what I like to see on the SE platform but I don't know what else should be done.
- Maintain an off-site resource, preferably a wiki-like where issues and events concerning the community and the greater causes folks are working on are mentioned in a timeline.
- Maintain a page and mention links related to the removed Moderator and the financial support they need for the legal case.
- Wherever the staff removes the links in a post you add back the links to the pages from step 1 or step 2, as deemed fit by you, with a note that that the link provides a context to the answer and optionally, with the mention that links to additional info are within accepted policy of answer writing on SE.
- If the pages are found reasonable to the author of the post, they might not dispute the edit with "this changes the intent". If they do, than you let go of that post. The author has spoken against your edit and there is no point in engaging further with them.
For clarity, I do not support reverting back edits which are done by the staff as a matter of policy. We achieve no good out of doing this. You risk being suspended and the staff would still continue with their actions anyway because this is their "job" to do, and given this a legal suggestion, it is likely they would implement this strictly and remove hindrances if needed be.
Find other ways. Please.
