It wasn't "free". We bought a "lifetime" package. I don't recall the details, but I ponied up a couple hundred dollars at a time when we didn't know textdrive was going to make it. I don't expect a lot of support, but I do expect uptime and courtesy.
Oh I see... then, I just wonder how they could eat up for life-time subscriptions for so long. After some Google searches, I've found that those plans are one off, and seems to cost $799 to sign up (http://hostingfu.com/article/joyent-lifetime-accelerator). If the terms was not changed, it now cost $25 a month on JoyentCloud to have the same thing with the SLA I mentioned. So it takes 31 years to compensate the cost of the $799 lifetime subscription to pay off. But the fact is that now they have "10 TB Monthly Bandwidth" (or unlimited depending on which web page you are looking at), I am just blindly guessing that lifetime users would get that too, right?
