Why not? Since the funds are just sitting there, why not accumulate an interest on them with staking?
I would also like them to start investing in more then just ICOs and would be all for them investing into passive income generating projects...
I have a suggestion for Iconomi.
Iconomi can increase the number of Lisk they own by voting for delegates on lisk, which will give some forged Lisk in return.
According to my calculations, it can amount to burning of 124K more ICN /Month. Which is a very good amount.
They probably won't since it will jeopardize the asset itself. In any case, these funds are meant to be used as funds, and not to be used for staking or delegation
