If you like to have a Linux router with every knob on a panel this is for you, if you want (and will have to) open the panel to tweak with the wires, not so much.
Found one of many mentions (sorry for the long URL): https://www.trendmicro.com/vinfo/us/security/news/cybercrime...
I heard something about software limiting the routers, so you had to pay for license upgrades to get full functionality out of their routers. Any truth to that?
Regarding the pay for a license to get the full functionality. There is no chance a home or ordinary office user will ever hit any limitations within a stock license. The upgrade might be needed only for the ultimate stuff in realm of BGP tunnels and stuff alike.
The 200 000 devices mentioned in the article you linked all had management port exposed to the whole world, which is something that should never be done.
