You are right when considering an individual. When you consider a group of people, the probability that all of them saw the vandalized version on Wikipedia site goes down as the number of people increase. With the offline version, it stays the same.

If you consider the case of disadvantaged children whom some of these projects aim to reach, the whole peer group now has the same vandalized information and there may not be a secondary source of information.

That's a good point. Ultimately it's going to come down to risk versus benefit.
