You can't have freedom of speech without freedom of wealth. The more Money is controlled by the government, the more it will be able to censor opposition and incentivize loyalism.
But you can't have freedom of speech with unchecked capitalism either as extreme wealth individuals/companies then can easily manipulate/undermine it.
This is especially true for countries without a constitutional right for free speech or such which made the mistake to only protect free speech from the government but not extremely powerful non-government entities.
Furthermore putting checks on capitalism doesn't mean the government is not directly controlling the money (I mean it's not the same as e.g. communist style planed economy).
To make thinks worse as long as a government still has any power they still can undermine freedom of speech even in mostly unchecked capitalism as they can subtle motivate the extremely money-rich entities such a system will produce to use there money to undermine free speech. Now some would bring here the argument that the markets self regulation will fix that, but I think it should be obvious this doesn't really work for many various reasons (like e.g. DRM, or just the simple fact that everything is extremely complex where it's close to impossible for a consumer to e.g. reliable not buy a direct or indirect nestle owned, to just name some examples.).
