Don't believe a word of it. Google will do with your browsing data whatever they (or their 3-letter handlers) want.

Also, don't save anything to the "cloud". There's not a nice, fluffy cloud floating around with huge amounts of data storage available. Guess who owns the data storage system that everyone thinks is a friendly "cloud"?

Yup. You sent your information straight to those who can use it against you. Instead... invest in a free-standing hard drive. Keep your info to yourself.

Now have your sister company delete everybody’s DNA data that you tricked them into submitting.

That's nice. So what about the parts or that data they already shared with 3rd party databases of companies not enjoined in this lawsuit?

First will do a command c, then a command v, then we'll hit delete.
