content: First let me say you're points are totally valid and there are much bigger problems than (probably trustworthy) vivaldi. The problem there is, you shouldnt just concede everywhere because other unrelated privacy battles are outside your control. Try to get privacy and security whenever you can and hopefully one day we will leave the dark ages of computer security. I realize I'm not the average user but I have compiled Firefox (albeit years ago), and I use it as my primary browser . No I'm not compiling nightlys here but thats not the only reason to like OS. Open sourcing a project in and of itself provides a certain degree of privacy/security and I'm trying to plug as many holes as possible in a leaky ass barrel that is my computing architecture and every single layer that sits on top of it. Same with my phone. I'm running windows and wishing there was an actually viable alternative. I love Linux to death and use it on all my servers but I cant install Hearthstone without a windows emulator so there goes my usability (i keed but you get the point). I dont have an alternative. With browsers, I do have a working, usable, open source privacy conscious browser that I can easily access every day, so I choose that one. I'm not going to switch to a potential privacy problem For crazy example a company with a closed source product could get a NSL that required them to include a back door. totally inside the realm of possibility as we all know. A browser would be a juicy target. How would anybody know? That cant really happen with firefox. It can happen with the closed processors, drivers, operating system etc. etc. but they all have one thing in common. They are closed source.
