Thanks for learning about citationsy.com! I don't publish with Elsevier since the Cost of Knowledge movement. I try my best to not publish with any publisher who locks the article or who asks money from the author (gold OA). But hear me well: it is useless to blame only Elsevier. Go for the academic managers who make possible this. Or the gold OA circus. Otherwise publish with arXiv or better try to make all your work available: data, programs, etc.
