I can not agree with the second paragraph of the first link:
To astronomers, flat means that the usual rules of geometry are observed - light not being bent by gravity travels in straight lines, not curves. But
since Albert Einstein proposed that the Universe may be "curved", the debate has been open.
Because of this picture:
The image is of Abell 2218 and shows gravitational lensing. The light from an object behind the bright lights (galazies) is being bent so you can see
some of it.
Unless I'm misunderstanding what they're saying, I have to say that they are wrong.
