They can only stop addon managers that scrape their own website. Meaning that once they have control of what is currently the twitch library and curseforge, they can act against addon managers which scrape from it.
They can’t however take any action against addon managers like Minion, which take addons directly from wowinterface and do not touch the twitch/curseforge code or addon library.
After doing a little more research, it seems their plan for their app won’t have in-game advertisements. I imagined it would be like their Hearthstone app, which works like that, but they say the ads “definitely” won’t appear in-game.
So I’ll take back that statement in light of new info.
They do, addon devs on Curse get some of the ad revenue, they have for a while now.
They can put them up for download anywhere. Curse is just the biggest and best known so that’s where most devs go. It’s like trying to sell your art on a random website when Etsy exists.
Overwolf gets around that by not being an addon that interacts with the game. It’s an overlay that basically appears over top of the game. I don’t believe that is what they are doing with WoW though. I could be wrong but I believe they are just going to be a regular app like the twitch app.
I’m a cloud/windows developer, and the curse app (and the addon section of the twitch app) don’t look that complicated. I bet I could make Something similar it pretty quickly.
Because the addon’s are on their server and if they don’t want a third part addon connecting to it, that is within their rights. You can manually do it because you will be using the cursed forge site which is part of Over Wolf. But third party addon manager will not be part of that network.
Why would they want to accept that responsibility? Not only does it require a massive repo and hosting service, but they would then be responsible for ensuring the addon’s are not something other than advertised plus a staff to handle an approval and vetting process. And we both know the second they did this and an addon breaks down, people would be here telling Blizzard to “fix their addons”.
Because we as customers deserve it? We shouldn’t be worried about some third party getting a monopoly or their client having malware or whatever.
Addons are pretty fundamental to modern WoW. Blizzard has more than enough resources to make a platform for them. The upside is happier customers.
You need only look at reddit and this front page or spend time in any guild to know there is a certain level of anxiety over the future of addons right now and there shouldn’t be.
