Re: Unfortunately you can, but...
But that's not the case with Netgear, because there are other managed switches on the market that offer the same/similar functionality without having to provide personal details/register their hardware (as well as older Netgear hardware). There is no clear reason why personal details are necessary, and are clearly with the intention (at least) of marketing customer's data,.Implied consent is not sufficient.
Netgear's forced registration policy certainly seems to be flouting EU GDPR.
