Setting DO Spaces files to Public for Django CKEditor

I’m using the Django plugin, django-ckeditor, which unfortunately does not work with S3 unless the following is set: AWS_QUERYSTRING_AUTH = False.

https://django-ckeditor.readthedocs.io/en/latest/#using-s3

The problem is that all files must be set to public to work with that setting. That plugin, in particular, has hundreds of directories with hundreds of files. So my question is two-fold.

Is there any security risk in making all of my css, js, images, and ckeditor files public?

Secondly, is my only option to manually go through each of these directories and change them to public? Is there a faster option?

Thanks
