A challenge for opensource today: The prevalence of cloud services & walled gardens helps minimize the meaningfulness of software freedom.
Free software started in an era where most of our software ran on our devices which we were free to reprogram (unless its e.g. a Nintendo). Early on PCs barely shipped with any software installed! If you updated that software to behave as you desire, you're the only one who could be harmed.
This is no longer the case today!
