Also, corporate licensing is a bit different beast for service providers. It would be the end of OpenAI or Antropic as a business, if it would turn out they use paid customers data for training, when that has been forbidden. Caution is fine, going full luddite is counterproductive.
Corporations can screw over consumers, however they do their diligence on corporate customers. Which also applies to kind of services that are used by paid customers and corporations alike.
Tldr; don’t ever touch anything with a ten foot pole, if it implies sensitive data, and the service doesn’t have significant corporate customers.
Luddites were pro tech, but also pro worker . And Msft and other orgs such as Dropbox and otter have been proven to use information.
