With a lawful warrant they can look at whatever they wish with my explicit consent and knowledge to make sure they do not exceed the law, because I have heard enough first and second hand horror stories to know how abusive investigators can be, particularly from ex investigator friends. I work with a lot of people in the security industry, particularly those in countries or organizations that might not take kindly to those activities. I have a similar responsibility as a journalist to protect my sources, vulnerabilities still under embargo, etc.
I however mostly detest how almost every third party SaaS sells out our metrics and data for profit, long term consequences be damned. The less I empower profit maximizing machine learning to manipulate me and my family the better.
