Purism has posted a rationale behind their disabling of the local and federated timelines: https://puri.sm/posts/opt-in-no-ads-and-no-tracking-solve-a-lot-of-problems-in-society/
They have also decided to reinstate the ability to submit reports as indicated by Kyle Rankin, their CSO: https://source.puri.sm/liberty/smilodon/merge_requests/4#note_30220
I have also updated my blog post towards the bottom with this information.
@brandon I don't see a problem with them not showing local/fed timelines, other than you are removing features some people might want. That's just a client-level thing, not an instance thing like removing reporting ability.
Caveat: *As long as* users aren't prevented from installing/using Tusky or some other client with their purism instance account, if they wish.
