That article has been posted several times and does not explain how Google “destroyed” XMPP - it assumes that XMPP was some hot shit everyone was using before Google and Facebook picked it up, when in reality it was used by next to nobody, most people who used it with Google or Facebook were just using it to talk to other Google or Facebook users, XMPP doesn’t support a lot of features that consumers now expect in messaging, and since Google and Facebook dropped it it has returned to being a niche FOSS thing - only now its advocates blame Google and Facebook for its failure rather than the fact it’s not a very good protocol and nobody uses it.
I’ve always been underwhelmed with DuckDuckGo as a search engine, and for context on that remark I use Bing as my main search engine.
