In Sweden, we have a meme that goes something like "It doesn't matter if it's untrue, it's still outrageous".
Essentially, you are complaining about something that is simply not the case. As you yourself said, this isn't Tor preventing free speech. This is Tor evaluating their commercial partnerships based on their values and whether or not they are compatible with the speech of their partners. So, it has nothing to do with Tor's stance on or facilitation of free speech. Therefore, there is nothing to be outraged about.
