Hmmm. Good point.
A spheroid is a special case of an ellipsoid, where stretching or squashing are equal along two axis. And no, the article was not specific. It says:
"If the microwave shell is an ellipsoid with an eccentricity (non-sphericity) of about 1 percent, then the WMAP quadrupole is exactly what it should be."
To me it suggests a spheroid. But maybe they are being sneaky and really mean a pulled and twisted universe - I don't know!
