Hey Yev,
As another data point, Backblaze has pretty much until this weekend to provide an update that includes "we have removed Facebook and are getting a 3rd party review for other security holes in our product". After this weekend, I won't care because I'll be on a different product.
This is embarrassingly bad, as in, I'm now embarrassed for recommending using Backblaze at my company.
Crap, I just realized I got Backblaze installed at two previous companies. Thanks!
