However, it was as much the operator's inexperience using a table saw as it was the fault of the table saw itself..... my opinion. Ripping without the fence was the error, if I remember correctly?
Anyhow, the landing area in front of the blade is too short.
Most likely the fence is too short and may not lock in place securely or not parallel with the blade....? You would need to test this in person.
It's designed to be light enough to carry around and that typically means it will be pushed around when feeding any thickness of material more than 3/4", again my assumption. You can bolt or clamp it in place however. Many folks build a plywood table around the small table saws to gain more capacity and to better support the large workpieces, another good after purchase solution:
It's not necessarily "unsafe" of it's own, anything with a high speed spinning blade can be considered unsafe. It's that the samll size, light weight and structural issues require additional devices or safety precautions. Skilsaw makes a new heavy duty worm drive saw that gets rave reviews. Notice how the saw is wiggling when they push those the thick laminations through it. It's not on level ground however:
