More generically, I think there's a big difference between releasing proof of concepts, and fully weaponized tools. While the latter is also usable by red teams, it also gives attackers (who often wouldn't have the resources to build the same) the weapons they need.
Personally, I like when people release proof of concepts, and hate it when they release weaponized tools. Especially when I inevitably end up reading reports where APT groups are using those tools.
