Interesting topic. Thanks for raising it, as I had never heard that issue before.
Some reasons not to use Windows 11:
1. Telemetry
2. Privacy concerns about your data.
Opening a spreadsheet in Microsoft Excel causes network connections to many foreign countries.
Your confidential data is getting sent all over the world, and being vulnerable if one of those servers ever got compromised.
3. Power consumption. After upgrading to Windows 11, I connected a meter to measure electric Watt usage.
I bought this one from Amazon for $33 US: P3: P4400 Kill A Watt Electricity Usage Monitor,
and it was showing very high electric usage from my 2020 year lower end laptop running Windows 11 when idle.
4. Lagging. Windows 11 seems to lag all the time, doing basic tasks. It feels like it's working on it's telemetry most of the time, and doesn't really give much CPU priority to the tasks the user wants to run.
5. Gaming: 8% slower on Windows 11 as compared to Linux.
It's worthwhile to consider the free open source alternatives:
No telemetry, no privacy issues, very low power consumption, no lagging (everything is lightning fast), gaming is fast, all free and open source, with forever updates.
