Thing is, with scooping up tags, the explorer still has to travel to all of those locations, and do the scanning/mapping. It's more a race to get to these places than a race to sell the data. Tag sniping isn't as big of a problem as people think it is, because in order for someone to do that, you have to independently discover it around the same time by accident, or one person needs to be directly aware of what the other has found, such as posting the system name here on the forum.
To put this in perspective, I think we need to remember that Exploration is one of the stated goals/roles for the carriers. I'd be more OK with it being a non-exploration feature, if it weren't for that. But if they want it to support explorers, then it needs to have the correct tools. It's like saying that it's great for bounty hunting, but you won't be able to rearm on it or sell your vouchers there. So then why have it if you're a bounty hunter? As it currently stands, it doesn't offer explorers much of anything. Repairs are pretty well covered with AFMUs and repair limpets. Fuel? Nope, we have scoops. Changing ships/loadouts? Rarely need to. How do we make our money? Selling data. So unless it gives you a means to get a little more efficient with that, then it doesn't support our role.
Again, I'd be less annoyed if they just flat out said it wasn't for explorers. I'd be disappointed, sure. But right now there's a mixed message here.
