I mean, a lot of these sound entirely reasonable. No way to report or block Micro.blog comments, the Sign In With Apple button didn't work, no way to delete an account you create. The way the author is trying to minimize these seems disingenuous. These seem like things I'm happy Apple is enforcing.The trademark one sounds like the main problem. Obviously, for example, Apple won't let you register an app called "GarageBand". In this case, "Inkwell" seems like a dead Apple trademark but that is still listed. But I do see that there are two iPhone apps simply called "Inkwell" and at least six more that start with "Inkwell", e.g. "Inkwell: Private Micro Journal". [1]
The reviewer is probably just trying to follow policy, when other reviewers have made exceptions. Hopefully there's a way to point to the many exceptions and get it approved after all? Is there a way to escalate/appeal to get a different reviewer?
