You obviously have the freedom to not air your views.
You have at-will employment in a lot of the US, so employers can fire you for any reason (except for some exceptions), or without a reason . I don't think this is a good thing, but there you are. This is a freedom for the employer.
If you have a right to a platform (i.e to not be deplatformed), that obviously limits the freedom of the ones supplying the platform.
So all of those points are actually freedoms, just not for the one being fired or deplatformed (the first point, freedom to be quiet, is obviously a freedom for the one keeping quiet. Maybe you meant something else?).
