I put together a list of open source CAD software a couple of years ago, but none of the options are quite there yet.

In 2018 Wisconsin passed a new free speech on campus law to be better able to punish people who protested conservative speakers. This chancellor brought an adult film actress to campus as a speaker.

I wonder if Delta Chat would work for you.
