We're happy to have any streams or coverage, and there's no black-out on that sort of thing. I would request that you use your best judgement with it in terms of what you show and how (with a little alpha footage disclaimer watermark, or whatever), but my assumptions are twofold:
1. If someone is an alpha backer, they want to see this succeed and are simultaneously willing to see the guts of the hotdog-making processes.
2. Given that there is a well-established template for how this works (AI War Classic), it should be reasonably clear where things are in progress for someone who's a fan of the game. Going "there's only X number of ship types??" when it's the earliest days is hopefully not going to happen, and hopefully any performance issues are things where we get reports and specs and can fix them (probably within a day or two), versus fatalistic "oh well I guess it's broken forever."
Anyhow, my assumption is basically that people in the alpha will take the alpha for what it is, and not go too crazy comparing it to a finished project; there's a reason it's not even in Early Access at that point, and it's not just that we're being snooty about who gets in. I'm really happy for people to do videos and livestreams and so forth during that period, and I'll be doing videos of it myself, too.
Anyhow! Monetization is absolutely a-ok as well, and Pablo isn't coming after folks with copyright strikes. Definitely better safe than sorry, but I'm not about to try to gag folks. I hope people will act in a collaborative manner with us (this and that needs to be better, and actually file a bug report) versus what happens with a lot of the developers that don't actually listen to any feedback and thus people kind of rage against the machine.
Cheers!
