If you have enterprise, you may have access to audit logs that might state when a user changed the view, but the last time I looked at enterprise audit logs, they were very tedious to parse through and hard to understand.
It is very common for people to change view settings without realizing that they are affecting other people. The vast majority of the time these changes are not malicious or laziness; they are done out of ignorance.
If people need to work in data views and edit filters, user education is crucial. Editors can change view filters, even though they cannot edit field configurations. In addition to locking views and using personal views, I use view sections to indicate which views are not to be touched, or only touched by specific people. I also name views with people's names so that people know not to mess with a view with someone else's name.
