(Isn't everything in our life "for now", given a sufficiently long now?) What kind of hostile commercial interest there might be, especially when the technology is protected by open-source licenses?

That such independence is - historically at least - usually the opposite. There are very few examples of where post acquisition such independence turned out to be the real deal.
Which, if that's the case, means that Sandstorm still is legally independent of Cloudflare, and the original Sandstorm devs can pretty much continue to do whatever they want with it. There would be some gray areas, like what will happen to future code or other IP they create for Sandstorm while employed by Cloudflare, or while using Cloudflare systems/resources; and of course their continued employment with Cloudflare may be contingent on their doing things with Sandstorm that Cloudflare likes, or at least doesn't disapprove of too strongly. But if the Sandstorm devs are just selling their future labor and not the company itself, they'll have more independence than they'd have gotten in an acqui-hire scenario.
