This is true. I suffered a lot until I learned that showing loyalty is necessary for having a career in a big company.

Most people don't care at all about doing a good job. They just want more money. To get along with them, you must help them get more money. If you oppose them on anything, they will make you suffer. And if they have the skills, they will manipulate and gaslight you. You can't make anyone do their work well. People work well when the organization is set up for it. If you can't tolerate your teammates' behavior, just move to a different team or company.
