@felichsdakatze @emilymbender I agree with the concern about describing "tech ecosystem". However, I think "information ecosystem" is not the "tech system". The information ecosystem is the means by which information is transmitted, so we could say it has been there for a much longer time than computer-based tech.
You are right though about the connotation that an ecosystem is something "natural", independent of us, and that we should protect away from us. I believe though that we should put down the connotation, not the concept itself.
