Why does Netgear fail to provide free DDNS but Asus always has and still does?

I have an Asus router (have used them for years) but was looking to go to the Netgear Mesh system, since it's highly reviewed.  However, Asus offers a free DDNS service, enabling me to access my webcams from my cell phone.  Netgear does not, instead offering NoIP as a 'free' DDNS that in fact requires answering monthly nagmail to renew it (i.e., it's free from $$ but not free from hassle and time).

Is there a reason Netgear is such a clear loser in this arena?  Of course, I will not be changing from Asus for this reason, but it seems odd no one mentions this as a reason to choose Asus over other routers.  Am I missing something?  What do all those people with webcams out there do to look at their cameras?  Am I the only one NOT paying for DDNS service?
