I will admit the openness is why I chose one disgustingly evil company over the other. You do have a point there. But there is no getting over the fact that Google is doing serious damage in many ways and just because you managed to uninstall all their spyware when you bought a pixel or any android device you are still funding that. You personally help them grow and become more of a problem for the Internet at large.
And I like that you completely glossed over the biggest point… That they both profit off of slave labor. And of course child labor.
But hey open software means slaves are not as bad right?
