I had no issue donating to Signal.

I use the Privacy app and generated a merchant specific credit card for Signal. This is the best way I have found to do online transactions. You don't even need to use your actual name or address when making a payment to a merchant since Privacy acts as a proxy for you. https://privacy.com
