That is absolutely true. Most companies have code review process that is totally full of nitpicking and trivial comments. I once suggested replacing that with static analysis tools to remove such comments and make feedback faster in our org, and was told that such code review is necessary for everyone. It helps people get promoted, makes people feel they prevented code issues, keeps the code review metrics looking good for the top level overlords who sit and monitor number of reviewer comments.
