To someone who is experiencing fear, though WOTC has done nothing to solicit that fear? I do think it's adequate. WOTC doesn't owe you anything more on this.
They've C+Ded a couple webcomics in the past. And numerous webtools and the occasional blog have been hit. And the guy making blueprints for Print on Demand minis. There is the constant worry that some lawyer might get it in their head that this stuff is costing sales or infringing on IP and start sending down takedown requests.
Does WotC owe me more? No. But if they want me to continue to support them and their efforts it would be nice. I've returned to D&D after abandoning it for other games for a number of years, and I'd like to keep supporting the game. But my support is not guaranteed. If I don't feel like WotC respects me or the fans then why support them?
There is an existing fan policy you can use - if you are still afraid despite that existing fan policy, that's not something that's their responsibility to cure for you.
Uh..they did. Now I think I am understanding what's happened here - you missed the news about the fan policy. Here it is, announced many months ago:
https://dnd.wizards.com/articles/features/fan-site-kit. And yes, if you're wondering at the 4e language here and there, it's because all Mike Mearls did is slightly re-tool the 4e fan site kit. But, he's the one that tweeted it's available for 5e, and that is still the kit.
I'm familiar with that kit and it's terrible. It's the same kit provided for Magic the Gathering only with D&D art assets swapped in. It's not meant for content generation, it's meant as a shrine to the game. It's not a retool of the 4e fan site kit, it's a reposting of the 4e fan site kit.
I mean, just look at what the Fan Site kit expects you to do:
We encourage you to use these materials, post your character sheets for Dungeons & Dragons, create fan fiction, display your personal artwork, and just have fun on your Fan Site.
They don't expect you to make a homebrew campaign setting, or post houserules, or manage you game, or write adventures, or post new races or classes, or anything of the things people actually do with their fan sites.
The Fan Site Kit is deeply and inherently flawed. First, it refers to the GSL for content generation. But the GSL explicitly doesn't apply to websites or forums, so it cannot be used to generate blog of website content. And the GSL only applies to 4e. (Plus all the GSL's other restrictions and prohibitions.)
Second, it doesn't include provisions for using any of WotC's other IP, such as campaign settings. The only copyrighted terms you can use are the ones included in the kit. Given the kit was last updated in January, that would mean refering to content like
Princes of the Apocalypse or
Out of the Abyss would be a violation of the licence causing immediate termination of said licence.
Third, it doesn't cover non-SRD content and terms like Mind Flayers or beholders. Again, referring to these causes immediate termination of the licence.
Fourth, it requires you to abide by the standards of the WotC site terms of use, agree to abide by those in exchange for using the kit. However, the Terms of Use were designed for content hosted on the WotC forums and blogs, and includes a provision that all content posted becomes the property of WotC. So if you use the Fan Site Kit you give up all copyrights to your content to WotC for free. (General Terms, Section 5. User Content.)
It is very much NOT the same thing as Paizo's community use policy, which lets you use the campaign setting of Golarion and all their IP for non-commercial fan reasons.
