Regardless of whether or not they're trustworthy, they're a grey market reseller, and they're inherently bad for the industry. GX purports to be a browser targeted toward gamers: grey market resellers are bad for the industry and bad for individual gamers. They disproportionately harm indie studios, and it's a bad look for Opera to be including them.

Notwithstanding that "deals aggregator" suggests that deals are being, well, aggregated. And they're not. They're just listing Eneba products. You could, for example, partner with isthereanydeal.com or gg.deals - that would truly aggregate deals from legitimate resellers.

I did turn off the aggregator. But it's worth thinking about who Opera want to associate themselves with if they want to pursue the "gamer" branding and "gamer" features.
