Now I'm thinking of all the ways I could get screwed here.
* Not being able to copy transactions from my bank account
* Not being able to easily send text to a read-later service (not sure if this necessarily depends on selectable text, but who knows, maybe selectable means the text isn't visible to these services now)
* Not being able to easily copy something that needs entering into another page
This reminds of sites that try really hard to NOT allow password managers, or even allowing pasting of text into form fields.
Pass.
