People rarely change their habits due to logical arguments, or ideological stances. Real change for normies happens when the current system becomes more painful than the alternative. Even with the potential to lose access to your media, there’s not enough friction yet. More fragmentation and more enshittification will eventually reach a threshold where normies start to find it inconvenient enough to consider an alternative.
The other side of it is people have short term memories. They’ll eventually forget about that time Sony took away their purchased content when there’s something else they really want to watch on the platform. We need laws that prevent companies from using the word “Buy” or “Purchase.” If we want real change, it’ll happen when the verbiage by law is “Rent” on everything and the blinders are pulled off so people can see that they own nothing and rent everything. For now the illusion of ownership is too strong.
