I'm as a linux user very reluctant to install anything proprietary that has such sensitive info as my network traffic and would rather use opensnitch or any other foss fork.
The same time I don't mind to pay for open-source, I donate several thousands USD per year to FOSS projects. But I guess I'm in a minority here and if you make the whole stack open-source you're not going to make many sells really.
Slightly? There are quite a few tin foil hat comments on this submission.
I tried to briefly explain a typical i-own-my-computer mindset regarding the linux monetization question from the parent comment.
I can pay for cool stuff I can trust, but the "I can trust" part is very tricky.
It's like the Nazi bar problem. You need to be vigilant to prevent the thing you rely on becoming yet another platform for Microsoft to exfil your personal data to NSA servers.
Everybody says this until they get fucking pwned at work or have their own data or children's data taken and used.
Then it's "not so tin-foily" and maybe it changed your entire life.
You're either paranoid, or a fool at this point.
