On the other hand, Plaid’s behaviour means that your data is not yours either, but is up for grabs by a 3rd party for which you may not have given consent to. Plaid is no Robin Hood (the story not the app) here.
Plaid is equivalent to a carrier, right? They merely provide the data to their client (whatever service/app you're signing into) and it's up to that client to decide how to use it.
