Complaining about companies will change nothing as long as there are people using them. Whenever the privacy topic comes up a few people come back with I have nothing to hide, or it's too difficult to figure out which is good, or my life is busy and I can't focus on that, or it's all fucked might as well just install cameras in my shower. All this means is that: a lot of people don't care or are too nihilistic to want to change, and neither of these groups deserves sympathy.
If you still use Gmail, you don't get to complain that they scan your email, or use it to sell you stuff, etc... If you use Alexa you don't get to complaint that they might be using other trigger words to register interest, or that your parrot ordered something by mistake. These companies have been making their position on all of this extremely well understood over the last freaking decade.
If you're in a position to let someone who's genuinely not aware of this and still uses Google, you can maybe consider telling them, if they change then that's a net positive on the side of humanity, if they don't then it's on them.
