Agreed. I think the key for me is that, at least under the original Presidential Surveillance Program, the providers that participated were not compelled to share their user's metadata. They shared it willingly, regularly, and in bulk. There is reference to a service provider backing out of this agreement a few years later, telling the NSA they would feel more comfortable sharing the data if it were compelled. It's not clear if this has changed since 2013. But assuming Mozilla, or Mullvad, isn't compelled to share _all of their data_ it seems unlikely that they would willingly give that up to a government surveillance program. I think ISPs have demonstrated they aren't trustworthy. For most people in the U.S., it seems, finding someone more trustworthy than their ISP is literally anyone who isn't admitting that they collect and share their private data. I would be surprised if Mozilla doesn't clear this bar.
