I can understand your concerns about our free service. As a user, I also avoid SASS many times and I want to have total control over my data.
I just want to clarify that our free plan has some premium upgrades from day-1. As of now, we have enough “silver” plan subscribers which are taking care of free users. So we are already “grabbing” (or getting) enough money to run this service.
media-node installation script is used like 1-2 times in a month. So I admit it might not be updated always. If a bug is reported, we solve it quickly. We are also using similar media-node for our free server. Rest, all headache can be skipped by using our installation service! We run human-checks and live-fixes so our installation service has more to it than simple running media-node installation script.
I already explained, our reason for using media-node. They are really our reasons. WordPress already has some plugins which might does what you need. You may try - http://wordpress.org/plugins/wp-video-posts/ . I did not check its code but from description it looks like they are directly converting videos from PHP.
We hope to add some new features to media-node this year. I hope, at that point, it’s existence will make more sense.
About “refund” - yes we do offer refund for all products as well as setup/installation services like media-node installations. It’s easier to offer refund than creating free version or “live-demo with admin access”.
