Hm… I genuinely don’t know about this one–depends on how Blizzard has dealt with such things before. I would argue that the actual guides aren’t really “Blizzard’s” content. Similarly, Twitch WoW streamers reserve stuff like ElvUi set-ups for Twitch subs, and that hasn’t appeared to be a problem so far.
Yes, but the difference in this is that if the ad is to be believed, then purchasing a membership unlocks content (full guides) within the addon. And I am very certain that paid content within addons or of addons themselves is a no no.
Blizzard hasn’t cracked down on people reserving their UI and WeakAuras packs for subscribers to their stream. So I doubt they’d care much about this either.
Trade skill master offers the same deal. You can use the addon and receive the database it regularly updates. But in order to access a feature “good deals or whatever they call it” you have to pay a fee.
I mean, is it against ToS? Probably. But what are they supposed to do? Send the lawyers on some random website that is probably based in a foreign country?
probably not against the TOS as you are not technically paying to access an addon function, or being advertised by the addon itself. Guides and premium website activity I believe fall outside of that policy.
Consider Curse is changing to a possible ad funded or sub addon manager. You can technically download said addons for free and manage them by yourself, or you can pay them to automate the management. That probably would not be terms breaking either.
I understand what you’re saying, though a subscription addon manager isn’t a great comparison. That would be paying to manage content already third party to Blizz, not paying for something directly tangible as in-game content (such as actually purchasing an addon).
