No, not really. Military planes were shot down, yes, but those operated at much lower altitudes. It's damn hard to shoot down an aircraft flying at 10k feet, you need something like BUK to even be able to reach that high. That's why these fly levels are generally consider safe even over (low-tech) conflict areas; this isn't limited to UK.
More readily available AA weapontry is only good against low-flying targets and it was thought at the time that the "rebels" did not have high-end military equipment from Russia. That's an intelligence failure, granted, but not irresponsibility by the airline.
