Some people have been saying this is because of bad UX on Google's part. Google is kind of in a catch-22 situation here. They want to upgrade how multiple users check their Gmail on one browser but no one wants to learn how use their new system (I got frustrated when they introduced their new UI to compose emails and had to show a tutorial on how to use it.)
