Why is everyone ditching Gmail?

Could you elaborate on the reasons why there seems to be a growing trend of individuals and businesses ditching Gmail? I've noticed several mentions of people switching away from the popular email service, but I'm not entirely clear on the specifics. Is it due to privacy concerns? Are there new competitors offering more features? Or is it simply a matter of users seeking a change in their digital habits? Understanding the motivation behind this shift would help me make a more informed decision about my own email service provider.
