You have to take into account the structure of academic research funding as well: grant based with typical horizon of 1-3 years and then funding runs out. If you put all your data in the cloud, who is going to be paying for the "forever-costs" of storage, egress etc after you grants are gone? For researchers this typically comes "for free" with their institutional infrastructure while for cloud it introduces tremendous uncertainty because typically they are required to preserve data supporting publications etc, effectively forever while few grants actually fund that.
