尽管Google 承诺 免费版的apps可以一直使用下去，不过确实在逐步减少不活跃用户---比如说你一年不使用的，就有可能被关闭了。
G Suite legacy free edition
Prior to December 6, 2012, Google offered a free edition of G Suite—also known as the legacy free edition—that had a reduced set of business features. As of December 6, 2012, Google stopped offering the free edition to new customers.
