Aggregators aren't scraping because they enjoy using headless browsers, the US doesn't let end users own their data and this is the industry workaround. I don't expect new players to change the system so much as I expect them to accurately represents it to those outside of fintech
There are? I think what you meant to say is “they haven’t worried much about key distribution, yet”?
We haven't seen brokerages expend significant effort on this, and the industry seems to be moving in the direction of providing more open access to APIs, so we're (cautiously) optimistic that we will be able to convince them to provide more sanctioned integration paths such that we don't need to continue playing cat-mouse with them.
Maybe the solution is just to have the jam maker give the neighbor a can?
1) Some brokerages have fairly sophisticated anti-screen-scraping protections, but their private APIs are comparatively undefended. 2) It's generally more difficult to create protective systems for private APIs, since there are fewer ways to fingerprint non-browser clients.
