Apology accepted and I quite understand! With Cubby's explaining this is CGL trying new things for previewing products, "A 34 minute video is a lot to chew through to find out the basics about a newly revealed product" may be criticism, but it is constructive criticism and relevant to finding out how this new approach is working and ways to refine it.
To be clear, even before knowing the intent behind it, I think the video itself is a great idea - its clearly a way to hype a new thing and get more creator and community engagement. The lack of any kind of CGL posting about the product excludes people that are interested but aren't in a position to watch or scan through a long video or simply don't absorb info from videos as well as from text - plus as seen in this thread, it even created confusion as to if this was a CGL or DFAW product! As a suggestion, a blog post/other CGL announcements going up shortly after the content creator debuts their "scoop" would actually help this process out. In this case, something like "Death From Above Wargaming Previews the New Battlefield Support Deck" with a link/embeed to their video and a blurb along the lines of "Coming Oct 8, the BSP Deck is a handy reference and play aid for using the abstracted battlefield support rules found in the BMM!" both increases the reach of DFWA's scoop (and of DFAW in general) and is a very useful summary of the product for people that are just looking for that.
To be honest, I think it is a situation where CGL is damned if they do and damned if they don't. There are some extremely vocal and critical folks in the community who never say anything positive no matter what CGL says or does. I imagine it's extremely discouraging to do something half the community suggests and calls for only for the other half to throw insults in response and vice versa.
Additionally, I've witnessed people not read what CGL posts, or only half read it before jumping to extreme conclusions, say "not good enough" to whats posted, or assume that what CGL posts is somehow purposefully misleading in some way. All of those things happen repeatedly. So in a lot of ways there doesn't seem to be a perfect way to communicate things to the community and have it be taken for face value without some kind of unwarranted "constructive criticism" being given.
That doesnt even include the people that don't follow the posts on the main BT site or any social media platform and then scream that CGL isn't doing enough to keep fans informed. The wolf's dragoons star force pack is the perfect example. It was announced in the main BT site, CGL's Facebook, Twitter, and Instagram, as well as BT's Facebook, Twitter, and Instagram. Not only that but the fan run "everything battletech" posted it on their Facebook and discord channel as well as sharing it to battletech international Facebook page and the classic battletech page all within 5 minutes of the announcement. Most things also make it to the battletech subreddit within an hour. But it didn't stop a ton of people complaning "there wasn't enough communication about it" weeks later. When what it really comes down to is some people aren't motivated to do even the bare minimum of staying up to date on the things they are a "fan" of while finding it easier to complain that personalized notifications aren't hand delivered by courier to their front door. At least that's the way it seems to my casual observations and interactions with the community on multiple platforms....though YMMV
