Because using the banks own API is provably less brittle better than scraping (as proven in Teller vs Plaid integration uptimes) and OpenBanking APIs are absolutely limited compared to the bank's native APIs - you can confirm both of these for yourself. Thanks for the conspiracy theory, but I don't own any Teller stock - I've known of Teller since 2015, mainly through Elixir (Teller is one of the first big Elixir-based startups) and the London startup community.
