It looks like Signal isn't as open source as you thought it was anymore

It looks like they had been working on adding MobileCoin support server side https://signal.org/blog/help-us-test-payments-in-signal/ .

Just a few minutes ago the server code was updated. Im honestly not happy about this. Feels yucky

Actually that feels like a reasonable reason for keeping the source temporarily secret.

I've been worried about it but now I see they had a good reason I have hope the behavior changes.
