"Virtualenv bin/activate isn't doing anything "wrong". It's just not doing it how the author believes is best."

So is it possible to do something wrong, or is it only possible to do something that another person (or you) believes is not best?

"So is this the "right" way? Probably not. Better is probably more like it ..."

So this way is better, but the other way wasn't wrong? How could this way be better?
