I service people for free because I can afford it despite I'm a company.
It's part of the philosophy of sharing value for free.
There are many services and products I use for free and I then make a donation to them because I love what they do.
So clearly it's not true, maybe just true for the companies that do not care much about doing something good for people with only optional contribution in return.
Also, plently of people at Google, Meta, etc feel they are doing good by providing free ads based services.
I suspect people with low income are way better off with free search, free maps, free docs than if each was $3 a month. It doesn't sound like much but their were definitely times in my life where $3 a month per service felt like too much. And yet, those services arguably provide extraordinary value for their users.
