Personally, I am glad to see Steemit exercising their stake in a number of different ways. For the first few years I agreed with the hands-off approach, but once they got below 30% or so, I came to see them as basically just a majority stakeholder with the same rights as any other stakeholder. After that point, I think it's healthy for the ecosystem for them to start making use of the capabilities that their stake brings them.

As you said, those with the most stake have the most incentive to preserve and grow its value.

My only reservation is that they need to make sure not to reconsolidate their stake above that 25 or 30-ish percent level, and further deconsolidation would be preferred.
