When someone takes clients' private information and shares it with other businesses without providing transparency over this fact, it is actually a breach of privacy. In terms of Signal, these breaches are both about their application and about their website, illustrating a complex issue with privacy in their business organization.
I'm not saying that the app is broken, I said that it handles user privacy unacceptably poorly.
But you are implying that this makes the app itself broken. I don't think this is proof that the app itself is not respecting privacy like their legal documents say.
I won't fight for them. I've never even been on their website. But this is classic situation where someone else is in charge of website and marketing. I wouldn't be surprised if slapping google analytics on a website was standard for every other "privacy focused" marketing product.
