We heard you. #HolosDiscover has been shut down, all indexed data deleted, and the source code removed. We apologize for the misunderstanding. Our approach was built with the deepest respect for user consent, but we understand it could rightfully be seen as misusing the indexable flag that many users didn't consciously enable. This highlighted a real conversation the Fediverse needs about default settings. Thank you for the feedback.

As an aside: I just learned about Holos-Discover, an AP search engine was taken offline by 
@HolosSocial after discussions relating to consent. The key finding was in https://toot.fedilab.app/@apps/116051469228002847

Yeah. I would reformulate to say that this is about protocol capabilities vs. these weird things we call "apps".
Can't check the Holos-Discover info, as it was taken down, but it seems to me that relying on an "Indexable" setting is an app-specific thing. Hence it can't be part of a generic consent mechanism.
When it comes to "defaults", the fediverse as a whole has a problem in that Microblogging is seen as something foundational to #ActivityPub, a given upon which all else is built. Protocol capabilities. But this is, should not be, the case.
Microblogging constitutes a domain, a set of user stories with well-define particular behavior. Or as app domains (Mastodon) + FEP practices.
