They've proposed a hard or soft fork of the software. Them owning these tokens may bias them to serve their own interests above those of the Ethereum project as a whole. Even if they remain completely unbiased, there is at least the appearance of conflict of interest which may harm the project. I don't see any problem as long as this was disclosed ahead of time.
