The only scenario that I think is likely for tech corporations are either legislative pressure, or a tech corporation for which user tracking is not their core competency (e.g. Apple) using it as their USP as a moat against Google and Facebook.
That said, there's a lot of user data at non-tech companies. Especially given that they're not particularly skilled at securing that data, a changing regulatory climate turns that data more and more into a liability. If, as a user, you can ensure that that data is stored at a trusted and competent party (potentially yourself), that alone would already be a major win, in my (personal) opinion.
