You could of course sue Google, but that's an extremely expensive and time-consuming option, rarely worth it for a mere consumer. Going to court certainly won't make your suspended account become unsuspended any quicker.
I get where you're going, but I think far more costly to them and advantageous for us is to simply show them that they are unnecessary.
If we can drop them so easily, they can't pull stuff like this anymore. It is possible to drop Google and Facebook.
They do this stuff because people _need_ them and they know that people won't just drop them en mass.
Its also possible to live without electricity and running water. This disproportionate power model doesn't work there because some people implemented regulations on them. I am beginning to suspect we need similar laws for this.
You'll very quickly discover why they are not at all alike.
2. You'll die in three days without water. You'll probably be healthier if you spent three days without Facebook.
3. I can't collect water for myself where I live. I suppose I could walk down to the lake, and manually bring up a few buckets of water, but it won't be safe for me to drink. I suppose I can also go buy bottled water, at a ~million-percent markup. There is no economic alternative for me to get water, other than through the water pipes laid to my apartment, by my water utility. I am a completely captive customer for my utility. My water utility has monopoly control of special-purpose one-of-a-kind infrastructure that is used to deliver water to my apartment. That is why my utility is regulated.
4. Unlike with my tap water, there are plenty of functioning alternatives to... Whatever it is that Facebook does for me. If Facebook shut down tomorrow, my life would be mildly disrupted for a week or two, and then would go on with little change.
On the hierarchy of needs, we have air at the top, followed closely by water, shelter, and food, followed at some distance by electricity, and way down the street, that we can barely make out, by grabbing a pair of binoculars, we will see 'Facebook'.
It's just not that important.
