  1. I may be wrong, but if I remember correctly in later books it become clear that alien behavior is result of them operating as so called celestial authority. Where central power is absolute, but it doesn't interfere in operations until something doesn't go as planed (what is BTW covert criticism of CCP). In fact initial signal is intercepted by disgruntled alien scientist, who actually could know about humanity and basically tell them to shut up, before someone else notice. Problem was that signal was send by other disgruntled communist scientist, who basically invited aliens. What reach central authority, which didn't take anyone opinion in consideration and basically send garrison forces to size Earth. Triggering the war.

  2. Before I even watch the video. When Dyson proposed his idea, he was actually not talking about rigid structures. But series of satellites, inspired by Star Maker by Olaf Stapledon. And to avoid misunderstanding, people tend to refer to is as Dyson Swarms. Some also make distinct Dyson Rings, as lower end steps in the design. Anyway, idea is legit. But it would not be a rigid orb, but multi-layer series of energy collectors and habituates, gradually evolving in something known as Matrioszka Brain.
