I work for a major NGO that is heavily involved in USAID contracting. Until recently, it was my job to manage US export compliance for all technical hardware leaving the US. While we did not work in Cuba, we worked heavily in other countries sanctioned by US. There are two things about this story that don't add up.
1) The US heavily controls the export of technical equipment such as laptops and cell phones, so much that individual licenses must be granted to each item, and each item must be accounted for every single year. There is an entire office established just to control these items, called the Bureau of Industry and Security (http://www.bis.doc.gov/). Failure to comply with such regulations results in massive fines (in the millions of dollars) for the contracting agency, and even imprisonment for the guilty individuals. The theory is: technical equipment could be use for "Anti-American activities" if given to the wrong parties, and under NO circumstances are agencies allowed to freely hand out computers or other similar things.
2) I don't see anything in this article talking about repercussions from the US government. For this person to just freely hand out goods means he had special permission that is very rarely granted to any USAID partners (or any other American for that matter).
It sounds like this person/agency was directly involved in activities that go well beyond USAID's mandate, and was a thinly veiled political maneuver. I don't think the Cuban government was targeting this person just because he was handing out computers, I think he was being targeted because he was supporting a subversive political tactic from a hostile party. Not that anyone didn't already suspect this, but just stating the obvious....
