The finger pointing has begun. Pointing the finger at Valve, at Bethesda, at modders, at the Nexus, at YouTubers. Have you really not seen this coming, at all? Evolve launching with $100 worth of day zero DLC? Buying games knowing the developers have said they won't release SDK's any more because it's "too hard"? Paying money to beta test games in Early Access? Pre-ordering games based on hype despite the developers and publishers enacting review embargoes? Users spending $220 million plus on mods already for TF2, CSGO and DotA 2? Of course this was coming. Anyone who's done any of these things has been complicit in getting us to this stage! I'll put my hand up and admit I bought DayZ stand-alone. I'm sorry, alright, I didn't realise they were going to be this bad and take this long!
The worry is with the introduction of Curated Workshops that free and open modding will be removed entirely, as in, it just won't be possible to do. You've seen the arguments before with developers like BioWare and DICE no longer supporting modding with their games, they say it's because it's too complicated for modders or because they don't have time to work on the tools, many users argue it's because they don't want mods to cut in to DLC sales. I don't know any more about it than you in that regard, but if you're running a curated modding marketplace and there's a site out there with lots of mods available for free (note: probably not the same mods, as that wouldn't make sense!) will you willingly let that continue or would you try to ensure all your mods were going through your curated marketplace? I guess it would entirely depend on the developer and publisher in question, but if you ask me, my main concern now is the DRMification and closing down of free and open modding, the concept that modding can only take place if it's done through one official platform to the detriment of all others. Because up until now that's definitely not what modding has been about at all.
