I am writing on the Zoom’s Missing Concept case study.
I think the case study is directionally right but inaccurate in how it arrived at those conclusions.
The concept of starting a meeting, sharing that link, and allowing people to incrementally join on the meetings without needing for everyone available, and being able to do so by sharing a URL, over desktop/phone browser is in fact a significant upgrade, and that was a big feature.
But, the case study is misleading to compare Zoom with FaceTime, Skype, Google Meet. These products were not really positioned to compete with Zoom. CISCO WebConnect was their actual parable, and felt like CISCO never really bothered for reasons I cannot comprehend, tbh.
CISCO WebConnect was built for exactly same use case, and they had even better features such as drawing graphics on shared screens, remote control etc. If I recall correctly, CISCO lost to Zoom on pricing.
During COVID in the US, organizations such as schools were significantly constrained on their ability to purchase new software, and Zoom really came through on a superior pricing model. Zoom’s setup was (and probably even now) is messy, and some security researchers called them out as malware (a bit tongue in cheek, a bit quite realistic).
Google Meet is a reasonable parable but they shot themselves in the foot tbh, like they had done with rest of their enterprise offerings. Like, limiting the number of audience, requiring Google sign up, no support on remote control, drawing on shared screen, glitchy video rendering.
Skype and Lync (Microsoft’s Skype makeover) both deeply integrated with hardware. You could pick up a phone call at your desk, and the status would reflect on the messenger, and it’s pretty cool/creepy depending on how you see it. But they kinda lost because it was hard to collaborate with anyone outside the enterprise.
Zoom killed Skype is an overstatement. Skype was getting cannibalized by Slack, and no one wanted two instant messengers. Microsoft eventually did another makeover to Lync, and now it’s called Teams.
The case study correctly points out that the ability to allow people to join meeting without signing up in browser, and share the meeting via URL, hop on/off without closing the entire meeting is in fact a conceptual change that in retrospect makes total sense, and why anyone would do anything otherwise. That existed in CISCO, and Google Meet. The problem was in the pricing model, enterprise lock-in etc.
