I hope you are right but I fear it will become a process of boiling the frog. Companies that are in the business of renting access to your data will get increasingly clever at moving in this direction in small incremental steps, providing some user benefit along the way.
We can agree that Zoom did a terrible job of rolling out their new terms, regardless of what their intention was. What other companies will learn from this is to improve the roll out.
Once local/private inference becomes more viable, there will be even more of an incentive for the companies who store unencrypted data to use it as a competitive advantage.
