YouTube search is one of those services that is pointlessly hostile. Most recently, they've removed the "order by upload date" filter, and changed the way that blurring works. Previously, sensitive videos had blurred thumbnails and a toggle to remove the blur (even though it had no way to never blur). Now the UI looks the same, but the "toggle" reloads the page without any filters, and adding a filter re-blurs them. So it's impossible to filter results and see unblurred thumbnails.
These changes baffle me. It's not even enshittification because I cannot see any benefit to YouTube at all.
