First time you rez this piece of ice, it'll do nothing unless combined with Satellite Grid or Amazon Industrial Zone. The first card will give it one advancement immediately so it'll gain deal 1 net damage, and the second will allow you to advance it right away after rezzing it.
Using Woodcutter with Amazon will cause it to cost 5 for the first rez and 1-2 more for the advancements. If used with Satellite Grid and Amazon you can give it 3 subroutines with the first rez, and in theory you could keep adding subroutines on it indefinitely. There are no sentry breakers that'll break all subroutines on a piece of ice, every one will cost 1 credit more. So, it could become something that no one will want to - or can - run through. This is it's advantage compared to Tyrant, which - if it was prominent in your meta - could be punched through by Morning Star for 1 credit.
The major problem with these two ice is: They are expensive for the fact that they do nothing at first and they have low enough strength that Parasite is a problem even without Datasuckers to kill them on the same turn as they are installed. You will spend your money and time and then they get trashed. Both pieces of ice are not bad if you're playing casual games where Parasite is not so prominent. But if it is around, they quickly become dead weight.
