Bad actors, especially state actors, will have no problem getting this data.
Everything that costs will cost to the degree that it costs. Putting the chocolate milk on the top shelf is enough to encourage children to buy less chocolate milk. The data you're talking about? The place I work at is the one doing the hard boots on the ground labor for aerial data, and from that perspective nothing is easy or free.
One can make great arguments about why people should have access to data notwithstanding all risks, but surely not that security by obscurity is mere illusion.
Easier access does lower the bar for amateurs and increase the risk of damage but these are two separate things.
GP said architects should anticipate bad actors and i'd add a "no matter their size". Putting the chokolate milk high up the shelf helps as long as children are small and dumb. Security by too-high-cost only effects poor, lone and unimaginative actors.
