I am not sure I understand? I have just checked and this doesn't get changed

See this post as an example https://iceshrimp.de/notes/a7gjrym3h4jkkuxu

User tells me the hashtags iceshrimp recommends are lowercase and he would need to change them manually, each.

He pointed me here to do a feature-request.

Maybe this is a js only issue? Testing on iceshrimp js it seems all suggested hashtags don't use any Capital letters whatsoever. All suggestions are lowercase, no matter if previously CamelCase Hashtags were used.

So, first of all this issue tracker is for Iceshrimp.NET, not Iceshrimp-js, which has ended development and is not accepting new feature requests, but anyway. I don't think it's actually possible to make it recommend camelcase, because how can it even be sure how the word should be written? Iceshrimp.NET currently has no autosuggestion built into the frontend, Iceshrimp-js however does have one and it's a relict of Misskey, which is why it works like that.

One possibility would be to just recommend whatever people have been using without converting it to lower case, but that's not what the issue is about

It is well understood, this is the iceshrimp net tracker. As there are no public instance (yet) it was not possible to easily verify or learn about the iceshrimp net behavior. So the idea was probably to ensure it behaves better than the old behavior currently does in iceshrimp js.

In that case this reners the report invalid. It's probably fair to close then and hope that should iceshrimp net ever add the feature, it does use what people actually used (instead of converting camelcase to all lowercase). Ideally maybe even using weight for suggestions by common usage to prever hashtags used more frequently.
