Kick isn't really a streaming site, it's a front started by the Stake bitcoin casino after Twitch changed policy to ban streaming bitcoin slots.
Stake had been handing out huge contracts to major streamers to show themselves having fun gambling on Stake, particularly xQc and TrainwreksTV. These streamers would act as if they were betting with their own money, including getting into six figure bets, without being clear they were on a contract that basically made it all upside to them even if they lost millions. The audience for these streamers slants young, and that didn't sit well with Twitch advertisers, hence the change in policy.
Train et all didn't want their golden goose to end, so they worked with Stake to create Kick, with Train as one of the cofounders, and xQc and others pulling their audience over.
One of Kick's selling points to streamers has been to be a wild west as far as copyright and content goes. They quickly took in all the streamers too toxic for other platforms, including people who'd done things like film themselves committing sexual assaults on Twitch. They've encouraged people to restream copyright content like marvel movies, and even porn.
I don't know what the laws are like in Greece, but considering this free for all approach it's not surprising they'd run afowl of regulations somehow. Frankly it's amazing Kick hasn't gotten nailed by some sort of major anti piracy action, but I suppose being based out of the Seychelles complicates that for copyright holders.
In any case, the point is Kick is an aberration. It's way too toxic for mainstream advertisers, so the only thing sustaining it financially is Stake paying people to stream gambling on Stake.
