We understand your concerns, though we have answered these particular ones multiple times in multiple places.
Please don't make accusations without presenting evidence such as that we're spying on anyone?!
We would not recommend anyone believe that open source = private by definition...though DEFINITELY it is the case that it's MUCH more likely to not have a backdoor and such. There have been attempts to insert backdoors into Linux for example that were caught *only* by chance! It's unlikely audits and such would have found them. So actually there need to be other ways like software to check network activity and others to ensure privacy especially for huge projects like Linux and Chromium where manual audits aren't so practical.
In fact, we have built our product to some extent to counter possible backdoors that could exist in Chromium and would like to strengthen those protections -- protecting against any outside calls (there are a bunch of Google servers at present we're blocking).
There are a few reasons we haven't been able to completely open source all our code to date -- we hope to soon & sorry for the delay. In the meantime, we have released and will release any files to anyone who wants to audit them. We're doubtful that anyone has really gone through the tens of millions of lines of code that are in chromium -- it's so massive -- but anyone who wants to audit that and or our code is free to do so. We've had many requests for files and for help with chromium which we've responded to.
We support Windows and Apple for the obvious reason most people are using their computers. We love Linux but its usage is still relatively smaller though we do hope to support it soon.
We did solve the epicupdater issue, now on uninstall it should be removed -- sorry about that.
We hope to offer installation location and search engine options soon.
We support EpicSearch right now as we've integrated it into Epic in a highly private way -- your IP never hits our search server, it's masked (the last octet is scrambled) then sent over the proxy to the search server which sees the proxy IP. Your search results are localized thanks to the masked ip address. This is far more private than just using a private search engine who you have to trust to delete your IP address.
We hope our philosophy and implementation to date makes sense. We're a small team, but we're working furiously to make Epic as stable and fast as possible and increase its privacy!
Thanks for your feedback,
Alok, Epic Privacy Browser Team
