Telegram was not even mentioned, even though it has video calls with screen broadcast capability, video chats with no time limit and no participant limit. Why ignore an app that's just joined the app club with over 1 billion downloads?
This article forgot to mention one of biggest negatives of Skype is its lack of native support to Apple's M1 & M2 silicon architecture mostly due to how slow at loads. Not only that Microsoft isn't putting much effort into the app as it is with Teams, they are only considering businesses but for the consumer at home, family friendly requirement its due a massive overhaul. Ever since M$ bought Skype its never been the same and MSN Messenger though it wasn't a big hit for video calling unlike Skype, it did have that consumer, friend and family fun feel which you could use add-ons and plug-ins with. Zoom is another great app best for business though - too much functionality for office collaboration - only if they had a family mode and business mode where it hides all the clutter of business tools despite having better webcam picture and sound quality.
