Yes. But it is becoming increasingly difficult with "smart" or "connected" devices. Sometimes you have to fill forms to access services or agree with EULA's with abusive terms. If you disagree with the terms, you become ostracized because everybody else from your circles accepted those terms and nobody is using your open-source/decentralized/federated network or services.

You can't expect common people to be reasonable and spontaneously boycott abusive vendors. Most people are not educated enough for that. Among those who are, most don't care.

We need laws to prevent this kind of abuse so vendors can't take advantage of people who are willing to share such information even if they are knowledgeable about its implications.
