"Sideloading" is the rentseeker word for "being able to run software of your choosing on a computing device you purchased". There is no reasonable case for an operating system developer having a say over what programs you run on your hardware.
Thanks for the explanation as I had no idea what this mean,I think we need to remember when you buy devices they are NOT your devices, you buy hardware, and a license to run the OS that dictates how the people who write the OS want you to do things.
And if you install another OS such as LinuxMint over windows 11 or 10, cash converters in Torquay told me that invalidates the Warranty. It seems better plan than installing the latest Windows 11 update which breaks ssd.
