You bet. Same with any other of these big companies looking at getting involved in crypto - Microsoft, Amazon, Facebook, Apple, etc. You can absolutely bet that all your transactions and purchases will be used to build a profile of your spending habits and purchases which will be used to target you with ads and other products, as well as sold off to 3rd parties and potentially even governments to use for tax reasons.

I also have concerns with these big companies even when their intentions seem good. For example, the new HTC phone which will have a built in wallet and potentially also be able to run a node. I would be very surprised if their code for this is open source, and you can almost guarantee they will be tracking your transactions.
