This is patently false. Some universities and even governments enforce whitelists of reference publications, and each researcher is evaluated based on how many papers he manages to publish on them. Failing to meet quotas has a negative impact on the researcher's evaluation and ultimately may result in termination. Researchers may not care if a paper they read was from GloriousJournal or ModestPublication or even arxiv, but researchers without tenure who need to publish to avoid perishing do care. If you're starting out and you manage to produce 1 or 2 papers a year, you'll obviously care a lot where your work will be published
