2011: Microsoft buys Skype for $8.5 billion, rebrands Lync to Skype for Business, an incredible branding manoeuvre.
2012: Skype peer-to-peer nature and end-to-end encryption removed.
2017: Microsoft launches Teams, competes with own product after driving Skype into the ground for 6 years with encroaching advertising, removing features, and abandonment.
2025: Skype shut-down.
What was the point? When MS bought Skype, they already held a majority market share in the IM market with MSN, which they also shut-down. Between 2011 and 2025 they lost almost all market share for domestic users to WhatsApp and Discord.
This series of events baffles me to no end.
