You are totally right. Still, the platform could be considered a step in that direction. For example, a further improvement of the terms and conditions could at least force the services to agree not to store any data. If I manage to find at least a service willing to use the platform and some users, it's definitely something to look into.

Edit: I will improve the landing page in the near future, to better show the purpose of it and also to make it less vague.
