Don't forget that those 715mb you take have to be delivered by someone running those servers at the other end, multiplied by the number of devices. Don't be a vandal on the internet. Don't be the reason for why we can't have nice things like community ntp pools.
If the NTP pool has an issue with what TP-Link is doing, they should talk to TP-Link. If TP-Link is unresponsive to their concerns, then they should be public about it. It is not the responsibility of random consumers to know about how two other parties interact with each other.
This appears to be entirely a supposition that the NTP pool cares that TP-Link is doing this, without any evidence from the actual people in charge of it are concerned. As best I can tell, this blog is not run by Ask Bjørn Hansen and neither he nor the ISC have voiced any concerns here.
