• The extent to which Signal’s server software is open source has been a point of contention.

You seem to be conflating browser technology (Chrome, Chromium, Blink, Gecko, etc.) and search engine technology, but they are unrelated technologies. I can’t imagine what your mental model for these technologies might be to create this conflation. Their only relationship to each other is that search engines are accessed via web browsers, and that web browsers often (but not always) embed a widget for calling search engines.

I suspect that the cancerous “appification of the web” has reached an advanced stage where people don’t know how to distinguish between client and server.
