Presuming that you translated it to every language:
* 3 billion people don't care because they don't use the internet
* 7 billion people don't care because they wouldn't be able to afford it anyway
* 7 billion people don't care because the question doesn't make much sense to them nor do they really understand what it is about
* 4 billion people likely won't participate because voting is not an activity they are familiar with and/or is not something they desire to participate in.
Direct democracy also has a pretty bad track record in producing just, principled, and reasoned results.
Vanishingly few of those people have any idea what a satellite is, let alone that they may be visible in the night sky. The vast majority of the global population leans on religion or superstition to explain natural phenomenon. If you know what a star even is, you're in the minority. You might as well flip a coin, because very few people on the planet would even understand the question.
I think you're right that the vote would be no, but not for the same reason you do.
I think many people reading:
> Would you like to have 10,000 satellites launched
... would stop right there and say "I have no idea what that is, so no"
