It’s definitely both. A lot of folks don’t understand that insects and shellfish are similar, and I’ve yet to see “product may contain insect meal / aggravate shellfish allergies” on things that have crickets or are processed in facilities that handle insect meal. So, the FDA likely needs to catch up. But, it’s also a cheap filler protein that’s easily grown, and companies are cheap bastards, so it’s going to slowly find its way in and push out more expensive protein options.
It should be regulated.
