There was an interesting article a couple of weeks back about why everyone is now using Zoom video chat rather than Skype. Ten years ago Skype was the daddy of video chat and even got added to the OED as a verb before Microsoft bought it for billions.
In the piece they talked about how Microsoft had to change the fundamental P2P nature of Skype in order to make it work better on mobile and smart devices, which introduced a level of instability to the platform.
They then responded to negative customer feedback by endlessly re-designing the UI to try and improve user experience rather than fixing the underlying issues, which had the effect of alienating their customers even more while leaving the real issues unaddressed.
Sounds familiar doesn’t it? 🤔
