The devil is in the detail. The linked mark 'consists of a stylized letter "X". The left side of the "X" is white and the right side of the "X" is blue. The shaded square carrier represents background only and is not a part of the mark.'
That mark absolutely doesn’t say “X” to me. If I saw that with absolutely no context, I would think it’s another generic brand logo with nothing unique or memorable about it except how like every other logo it looks.
