Digital copies on consoles still get 30%, and console agreements may include additional royalties beyond that.

There is no way, on any major console, to "opt out" of the fee.

Mac has the same options available to developers as Windows.

Steam's third-party redemption mechanic is notable, and awesome.

On Android, different third-party stores have different fees. Samsung, for instance, charges the same 30% as Google. Epic's store charges 12%.
