What's the consensus on sharing raw data?
I'll share some thoughts with you as someone who has made all of his research software publicly available for the past 20 years.

My experience is that the risk of others "scooping" you by taking your data (or code, in my case) and doing analyses with them that lead to important studies is relatively small. The likelihood that they ask you to participate in such studies -- given that you know the data, how it was collected, and how it was curated -- is, on the other hand, relatively high and may lead to you writing papers you never dreamed of. So there are substantial positive upsides that, in my case, have always made it worth my while putting my work out there.
