If a smart meter gets hacked it's not unreasonable to imagine the local logs are compromised. This is a bit like all the arguments against voting machines but in a less concerning setting. TOU rates are a thing you can get with pre-programmed meters. They may not benefit the utility company as much as tailored rates but they probably have 90% of the benefit while having 0% of the privacy implications. The companies don't even have to sell the data, they can just mine it for information, such as which rate to automatically put you on once your contract finishes to make the most money out of you etc.
