One should not forget the reason for this growth though - the issues with privacy and users' control of devices on windows go back at least a decade, but most of this time nobody cared. It was only when Microsoft locked a lot of old computers out of Windows 11, Windows 11 proved a buggy slow mess, the google search results went down the toilet and the amount of adds on YouTube increased several times did people start to talk about "de-googling" and moving to Linux.
People are switching to Linux now because it works better. The privacy is still a nice-to-have bonus.
