Alex Jones has the complete and total benefits of free speech - he can continue saying whatever he wants without any repercussions from the government. Apple making a decision like this isn't influencing free speech in the slightest.
This seems like a Bad Article. It's pretty apparent from the maths that we are:
A) Very close to the critical density right now that would give us a flat universe
B) That we will rapidly diverge from having a flat curvature with a deviation from that critical density
C) Therefore at the start of the Universe we must have been even closer to 1 than we are now (and we're pretty close)
The way we measure the flatness of the universe using the CMB and Type 1a super novae is super interesting (especially for someone technically minded), and definitely worth checking out!
