No, Brave Origin’s changes can be replicated using group policies, but it works differently and depends on how you installed it.
When you install Brave Origin standalone, it removes the Web3, AI and other features at compile-time so it’s not included in the browser. When you upgrade from regular Brave to Origin, you get to pick and choose which features to enable in a more straightforward manner in a dedicated settings panel.
I think Origin is an interesting idea, not sure about how feasible it’s going to work out in practice as the price is a bit steep and paying to remove features will rub some people the wrong way. Having something like a minimum value and letting you choose either that or more could be beneficial, it would be close to a donation with perks.
