Stepien Rules didn't allow them to protect that pick, so they didn't have a choice. That pick also only had a 2% percent of winning the lottery that year.
This is what I got from Stepien Rules
In fact, all of these questionable moves led the NBA to institute what is commonly known as the "Stepien Rule," which states that a team (usually) cannot trade its first-round pick in consecutive years
Doesn't say anything about protection
Is there more to it?
