Chopping off limbs to gain separation from Oracle or affiliated entities would be quite reasonable, imo. avoid risking a connection in the first place is a great idea.

On the other hand, what is it you're planning to do with this tool? try it out for a day? use it for a single project? adopt it as the central feature of your life from now on and start arranging conferences and religious observances centered on it?

The assessment of risk should include how much value you're risking. Poke at it for one demo job to see if its useful may not be unreasonable either. "purity" doesn't demand utter ignorance of the sins available.
