I'm going to come out and defend them here. Most of that stuff was on
Atlantis. Their city. Where they would be the only ones looking at it.
More to the point, in the 'prime' timeline, the High Council securely locked the city behind them, expecting it to eventually be flooded and destroyed. For all we know, in the pre-Before I Sleep timeline, Melia went around clearly labelling all the dangerous stuff with Ancient post-its, but decided it wasn't worth the effort when they decided to seal the city forever. Janus altered that.
Similarly, they pounded the Asurans, who they thought were dangerous, into literal dust. It's not their fault that Oberoth et al managed to survive.
The headsuckers had precautions that only certain people could use them - we presume it locks out jaffa, but it might simply be that they only work for the ATA gene, and that's why they sucked O'Neill, expecting him to be a full ancient.
The only
really iffy thing they left behind was Dakara, and I assume that the 'puzzle' on that had more to it than we saw, simply because that's a stupid way to lock something.
When we actually see the Ancients' systems, they are
very well designed. The headsuckers autopiloted O'Neill into being able to survive both times, the Asurans had safety protocols in them, the stargates have innumerable safety precautions, their weapons are locked by the gene, and the starship
Destiny is doing its damndest to keep itself and its crew (going so far as to keep internal gravity and things on for them even in total freefall) alive. One group of Ancients, before ascending, went so far as to build a great storehouse of weapons and treasure and seal it away, leaving only a fiendishly complex puzzle that requires understanding of their language to work out (the Clava Thessura Infinatas).
A fully developed, non-experimental piece of Ancient technology seems in all cases to be safe.
