Stolen? C'mon. It is similar, especially so with that color, but it's more of a coincidence. There were many colour variants of the logo made and this one was chosen, and I HOPE to God it wasn't because of the damn eggplant emojis.
Thank you for your concern. As noted above, while there are some similarities between the logos, ResetEra did not copy the logo of upside.com. The ResetEra logo is a stylized R that looks like an arrow. Closing this thread now.
