"We love a clear time indication, and Helvetica seemed to be the clearest typeface for our display."

No, I highly doubt you did any research. Helvetica numerals don't work well here, especially with sloppy kerning.

"We thought it could be interesting to add some useful informations without distracting you from watching your game."

Like the glitchy animation for showing/hiding scores?

"It’s not just a trend: infographics, pie charts and diagrams participate in your daily inspiration."

"participate in your daily inspiration" sounds terribly awkward.

Very hard to take this serious.
