The extension isn't storing any data from Zillow. Bigger Pocket's proprietary calculator pulls the data from Zillow as well. I think as long as you aren't storing or trying to make it proprietary it is better.
I installed the extension but when I click on it (in Zillow) all I see is an EMPTY popout panel ...
Hey, interesting. Make sure you have a home opened and it should populate with the charts. If that doesn't work feel free to send me an email at caleb at homescope.io and I can help you out :)
Sure - will do.
IMO the appropriate response to this is to open source it, once the source is out in the wild then there's not much they can do about it.
That puts Open Source in an antagonistic position, which is overall harmful to the ecosystem.
