Maybe advanced aliens cultures also have an advanced empathy towards developing civilizations, humans have evolved empathy and while not perfect it is more advanced than most of the less intelligent animals on earth. Yes we still decimate lesser creatures without much thought or caring but we also are able to show compassion towards suffering and endangered species and humanity seems to be working towards living with less impact to the biological systems that have nurtured our development. I like to think that any advanced alien civilizations would have learned to live while causing as little impact as possible to other evolving lifeforms. We may seem boring to them but with space being rather large, having anyone to talk to or learn from might be worth keeping rather than destroying them or sacking the place for raw materials.
