If you're unhappy with how a company operates, then by all means feel free to rant. Go elsewhere. Google may be the largest search engine on the planet right now, but there are other options available. But to claim that you have a right or that they have a responsibility is just untrue.
Google hasn't removed your domains from the net.
Google hasn't stopped you from having sites on those domains.
If you're listed in Google, you're likely listed in other search engines as well.
If you're complaining that you're going to lose money now that you're not in the search results from Google, then here's my analogy:
A man builds a private road.
Another man builds a business on that private road and begins to profit from the traffic along that road.
The man with the business begins to rely upon the traffic in order for his business to survive.
The man who owns the private road closes the road.
The man with the business stops earning money from the traffic on the road.
Did the man with the business make a good business decision?
Should the man with the business be able to justifiably cry foul on the man who owns the road?
