Re: Facebook (inc Messenger), Google (inc Alexa, Android, Chrome and Youtube) and Twitter..
Minor pedantry: Alexa is an Amazon product. Google has a thing that is like it, called Google assistant. It's the one that does even less and constantly sounds angry at you.
Also, even when a consumer understands the "free service means you are the product" idea, they often don't understand "I bought a hardware device but the software on it still treats me badly". Another battle to be fought.
