Removing Option to Make Contributions Private with Commenting Plugin

Hiya, We’ve a Covid-19 collection project underway and I’m finding it quite the challenge to remove the checkbox that makes contributions private. Some other user comments around similar issues, including adding some code aimed at preventing submission when “Make Contribution Public” is unchecked, haven’t worked. Any ideas? The “make public” checkbox creates a conflict with our terms of service, which clearly state that the submissions are to be made public.

Thanks!!!
Molly
