How Zoom works [slides]
Title is "How Zoom works".<p>It's a good article with valid points but nothing about Skype.<p>The editorialized title "Turns out Zoom isn't all that different to Skype after all" has no appreciation for how hostile Skype's technology has become in the past 10 years. It went from nicely working Qt program that worked well on OSX, Linux, and Windows to Electron beast that maybe works on Windows, could possibly be mining bitcoins on OS X (judging by how much it spins up the fans), and I think it stopped working on Linux altogether, replaced by a web client.
