First, let me clarify a few things to eliminate any confusion:
2-year warranty - This is not something you have to worry about. This is out of our pocket and is something we'll handle on our end.
6-month SLA - Unlike the warranty, this starts at the time the file was submitted, not when a customer purchases. This is just a formality to allow us to issue refunds on your behalf if your file becomes broken and you're MIA (inactive for several months, not responding to our communications). This doesn't mean that once you're gone for x amount of time, we'll refund or take over your file. In fact the SLA is not long enough to realistically qualify for SLA due to inactivity. I hope this puts it in perspective for you.
Invoking SLA- If the file becomes broken or support requests become ignored and you're unreachable, we may opt to issue that customer a refund. This is not something new. We've done this from day 1, it's just now in writing. This rarely happens, just so you know.
Conclusion - Despite the scary language in these terms, it's just there to eliminate legal liability. Everything mentioned is things we've always done to ensure a positive outcome for all parties. Your IP is safe, just as it always has been.
