What I mind is that I can't take Mozilla seriously at all.
They keep trying new projects. I laugh every time because I know it will be gone in six to twelve months.
Right now Mozilla is offering VPN service. Theoretically, I am the ideal customer. I care about privacy and security and make good money and have been a devoted Firefox user for nearly 20 years -- ever since Phoenix 0.2! And I trust Mozilla 100x more than the competition.
But I've never even glanced at that service. Why? So I can have the rug pulled out from me in six months? lol.
For me to take any non-Firefox project from Mozilla seriously, I'd need to hear some kind of commitment from Mozilla to supporting it for the long haul.
