Yes,  responsible XRD holders should stake their XRD to good validator nodes as greater stake provides greater protection for the network against Sybil attacks – and so the Radix Foundation (and its subsidiaries) stakes tokens for the same reason.

A portion of these tokens are delegated to nodes operated by Radix Token (Jersey) Limited, which may, as a result, be selected as part of the validator set. 

The Radix Foundation subsidiaries aim to stake a total quantity of XRD to Radix Tokens (Jersey) Limited -operated nodes that are no more than 25% of the total XRD staked at any given time. This is well short of the 33.3% threshold which would confer the ability to disrupt the network (even by accident) and make clear that control of the network always belongs in the hands of a decentralized community.

In the rare event that the subsidiaries are required to stake to community nodes, any staking above the 25% level is intended to be distributed across the broadest possible selection of validator nodes that they believe are trustworthy and performant.
