Because if the 2nd version has the spider symbol on his chest, it'll most likely sell better than the 1st version, as fans prefer Venom with the spider symbol, like fans of Thanos who didn't buy the hot toys Infinity War version, because they preferred the armored version........It's not even that you would have to worry about. They're not gonna produce another Venom figure if no one is buying the first version. They'll see that interest is low for Venom so why would they make another one.
