First of all, "free and open source" as in libre, does not necessarily mean "free as in beer". You are perfectly free to pay for FOSS and FOSS makers are free to charge for it. Is that clear?

Second, "FOSS = safe" from a privacy perspective is not nearly the reason you want FOSS. You want a FOSS browser for many, many reasons that are above and beyond privacy assurances.

Thank you for coming to my TED Talk.
