There is no general Stack Exchange policy. The general trend is to only ban clearly illegal content. In other words, by default, if it's a grey area, it's allowed. See these threads on Meta.SO:
- What is the policy on discussing OSx86 or Hackintoshes?
- Technically valid answers that raise questions of morality
- Policy regarding questions related to unethical or “shady” practices
So the decision to allow Hackintosh questions or not is up to the Super User community. For a long time, the only answer to Are “Hackintosh” questions allowed? was Diago's vehement no. Note that although Diago was a moderator at the time, his being a moderator is not what carried the decision: what carried the decision was the community consensus.
Later Arjan posted a defense of Hackintosh questions which now has the score +8 to Diago's +10. So the SU community no longer has a consensus. Nonetheless, the present moderation policy shouldn't change unless there is a strong majority in favor of the change.
Note that Arjan's answer should not be deleted, since it represents the opinion of a part of the community.
Disclosure: I personally support Hackintosh questions, but this answer is not in defense or support of Hackintosh. It is about Stack Exchange policy.
