There is a complicating factor. Universities are not your average top-down hierarchies. While some aspects of the work do belong to the employer, other aspects are yours (or you PI's), and they may follow you to your next job. While administrative matters and sensitive data tend to belong to the university, everything you create as an academic is usually yours.
It's pretty common, particularly among researchers who do not handle sensitive data, to have a burner laptop for accessing university resources and personal devices for the actual work. Many people also use personal email addresses for work. Work email rarely survives changes in employment, making it too short-lived for many purposes.
