I took similar approach a while ago. I don't run google ads and I am not doing any business with them but I have lots of important data on my Google Drive (personal backup) that I really wouldn't want to lose. One day I read a story of a guy who had his account shut down for posting a video (innocent in his own claims) to youtube. As a result he lost access to his gmail and Drive too. This was a wake up call for me as I realised that I could be denied access to my data for whatever reason. I have several additional copies now, both on local hard drives and different cloud providers.
