It may be coincidence, but just earlier today, I had to use a photo for display pic and default crop won't let you keep the whole photo in original aspect ratio, so I installed Lightroom to do resize but filling a blur. I believe this was my first time installing the app from play store, I signed in through Google login, I was surprised to find some 40 to 50 photos of absolute stranger synced to my email! I don't know who that person is, I assumed they may have put in my gmail instead of theirs, but it's stupid that they would start associating backups without verifying the email! Adobe has lost any respect it had. I will never trust them with my data.
That's true in theory. In practice however, I've had success with figuring out a service that leaked my dotted address (I used a dot because the service didn't validate email with plus). I think this is often the case too because, spammers don't really bother validating emails by postprocessing etc. and just sell the emails in bulk in shady markets
