ShaikhMuhammad You are talking about too many ads and bloatware.
Yet in reality the only thing they added is a randomized wallpaper for the lockscreen which also displays an advertisement fitting to the wallpaper image.
A feature which is disabled by default and need to be enabled manually by the user.
I am not happy about it either and have to say it’s sad seeing them spending time developing such a feature, while other, long requested features remain unanswered, but some people react as if they’ve loaded two dozen pre-installed apps into the OS and the new OS version will bombard you with ads in every single menu.
