A more charitable framing of the situation is: the for-profit company is because people always complained about Gitea "why is it developed on GitHub, not your own hosting" but that means money has to be involved in the cloud hosting project; it is just the same Gitea core developers it has always been, not a takeover.

The "open core" (Gitea Enterprise) is not Gitea, it is a downstream fork by CommitGo, who you can pay for contract development for custom features. The features are expected to be upstreamed, there are open PRs, they just don't yet meet Gitea's code review standards. You can run them from the PRs if you like.
