Crony capitalists (what I would call mercantilists) certainly do not care about the will of the people. They are tyrants who hide behind a word they are corrupting.
However I will defend to the death my right to exchange goods with you. I'm assuming you and I are just normal citizens who don't control multi-billion dollar businesses?
I'm going to use the first definition of capitalist I found on google:
"a wealthy person who uses money to invest in trade and industry for profit in accordance with the principles of capitalism."
As we know there is a huge spectrum of investment strategies, from VCs to Bond holders etc.
Some capitalists like VCs, absolutely value market freedom, others likely don't, but it's too large a swatch of people to generalize by saying they don't care about economic freedom.
