This is similar to T276393: Reply widget opens for users who can't edit the page, but I would argue that that task was closed prematurely.

Currently talk pages that can’t be edited by anonymous users, for example, look like this:

They do not have section editing links, but they do have [reply] links next to every comment. In my opinion, there is no argument that justifies a different treatment here. You could argue that edit section links should be shown anyway because a section might be from a transcluded page, but that’s not how it worked before when DiscussionTools was a thing, so to me it seems like it would be more jarring if you’re able to press [reply] and get an error message than if there would be no [reply] links on pages like these. Consistency in the interface is usually important, and this seems inconsistent for no real reason.

Maybe the solution might be to start showing [edit] links on semi-protected pages, as well, too. I don’t have a real preference any way or another (other than the fact that section editing usually takes you to another page, so it’s even more jarring as interface goes). But as a user, it is weird to discover that this tool does something different for pages I can’t edit from the rest of the interface (which, in simple cases, indicates that that is the case, and, I would argue, should indicate it more with things like Titleblacklist etc.).
