QQ mailbox began to support GMAIL collection

Today into the QQ mailbox, found that there is a new function, collect GMAIL. This is the latest support, also support to charge others such as 163, 21CN and so on. You need to fill in the address of the POP (accepting server). I wonder if this feature will affect other emails? I have always used QQ mailbox, because every time I log in to QQ first, QQ mailbox is relatively convenient, online you know there is no new mail, compared with GMAIL, QQ mailbox spam is much less. Unlike GMAIL there are thousands of spam, to find a serious mail also have to turn around, a little boring. I think we should also bind all mailboxes to QQ, so as not to miss important things. I don't know if GOOGLE will use the issue to affect GMAIL? Of course, I don't know about mailbox monetization.
