I think this is a legitimate concern. That’s one reason I only buy MacBooks. I trust Apple more than other companies.
Any particular reason why? Apple always seemed quite anti-user to me with "you are holding it wrong", walled gardens, incompatible ports,...
So whilst Apple have been putting anti-tracking features in their products [0] Lenovo have been putting putting rootkits on their laptops [1] in theirs.
Personally I think I'm going to move to a Dell XPS 13 with Ubuntu.
