If your concern is data _loss_ as opposed to data _ownership_ you can still use Google all you want as long as you use it redundantly (backups, separate domain, &c.) What you're saying is more applicable to people who want Google not to see their data.
Of course they do. Every strategic decision the company has made over the last two decades is to try to secure a monopoly on your data.
You make it sound like it's easy to run your own full stack of all web-connected applications. It's not. The cost is INSANELY high. So your real choice is whether to use one company, or dozens of individual companies for every individual service. The latter protects you against the risk of something like this happening. But it comes at a day-to-day expense which will far outweigh the prevented risk for 99.9% of people.
