I don't want to login/signup/copy to or copy link.

I'm using a personal setup with a Plus account, not planning to upgrade further. So within the Plus Account...
I set this up to let a group of people view pdf's, photos, mp4s. NOT to link to them; they can share my link to the folders. I'm giving out a VIEW link and it allows downloads which is exactly what I want.
I do not want them to join my folder. JUST to view them online or download them.
From what I've seen every screen shows the line So&So shared this folder... (which is fine with me but the next part is not) I do not want the to Log in or Sign up.  
&
I do not want 2 or the 3 button/boxes below that: Copy to Dropbox & Copy Link — because I don't want them to share the content.

Does anyone know of any tip or trick to either hide these or nullify them? (Without an upgrade because the fees jump too drastically for this project.)

I should mention that there are many friends that will View this content and Share it via my own link so giving each person a link would take major time. It's a privacy/respect-the-people thing.

Hoping...
