Technically can pony up for a Enterprise account ($200/yr?) and have protestors install the app after trusting the Enterprise org. You just have to host the IPA on a site somewhere. If you want to build the source code and install the app to a device, you still need at least a Dev account ($99/yr) and macOS+Xcode. Without an account you won't have the provisioning and certificates to install on a "Dev" device. You are also limited to just 100 test devices I think under a regular dev account. Another option is to crack the phone, then you can just go through third party repos to fetch the app.
