Many people confuse this, but being critical of ethical problems with the way technology is built in practice need not have anything to do with being anti-technology in general.
We should simply not allow that, and let big companies just develop the hardware.
You are free to deal with these companies or not. Whether you agree with these companies and their ways is irrelevant. This is same as not agreeing with another persons' religion, you are free do choose a way to lead your life, don't try to force your way upon others. Others happily share their data with Google and reap the benefits of a very helpful Google Home assistant.
Direct your efforts towards educating these people about the potential downsides, yes, but don't try to use law or other forms of powers to change their ways. That is not freedom.
Don't get me wrong, I love the GPL, I love free software! Choosing a license though, GPL or proprietary, is entirely up to the author of a piece of code though. Forcing open licenses upon authors is detrimental to freedom in general.
Worrying or not worrying about it has nothing to do with the ethics of breaking the GPL (or any license).
Absolute freedom does not exist. Every kind of freedom requires sacrifices.
