Please learn how to read patents.
As bad as all the X + internet ridiculously broad patents are that doesn't mean they all are.
This one doesn't remotely cover the broad concept of balloon networks nor the broader concept of balloon maneuvering as commentors here think. This one is narrowly written to cover a method to create such a network with broad stable network coverage by taking advantage of very high altitude weather behavior and is carefully drafted to stand up to challenge.
If Google's implementation fails to use any one part of the independent claim, they're perfectly free to do it. The dependant claims people are getting excited about place further restrictions on how the actual invention could be implemented.
You can safely launch your own balloon network without getting sued by them by for example staying below 40000 ft
