content: Well other than all of the malicious reasons, it's good for companies to record things like product usage when appropriate to help the company study their current product and how it is used.  If you and I bought the same vibrator somehow you might use it 8 times in a day whereas I use it 8 times an hour. It's useful to know what an average usage of your product is like. This helps the team who created the vibrator plan for future products, as well as provide an honest feedback on their current product. Imagine asking a group of women to disclose their average vibrator use - you can imagine how intrusive this survey would be and the amount of answers that are untruthful or exaggerated.  That being said, I think it's creepy that someone can look at your vibrator from the internet and tell if it's being used. It should be readily disclosed to the consumer, possibly anonymized somehow
