This ICE is very similiar to Enigma, it is neutral, has a Strength of 2, one taxing subroutine and one End the run.
So it has the same weakness as Enigma that it does not cost Yog.0 anything to break it and the runner will probably only hit it once but does cost one credit more to rez, which can be huge in the first turn since it often is the difference being able to rez one or two ICE.
The problem with Datapike is that you need to play it in a deck with strong early game economy that does not have or gain bad publicity (since it negates the tax) which means the faction that would use it the most, which is Weyland, does not like it. For NBN and Jinteki it is often too expensive for its effect and HB has better code gate options to tax the runner.
If you ever play a Weyland deck without or little bad pub or a NBN (or maybe Jinteki) deck with above average early game burst economy were you would play Enigma than you should give Datapike a chance... in all other cases it struggles to much with its many restrictions.
