DRM (digial restrictions management) can be implemented in freedom-respecting software, there's no obstacle to that, but it's not effective in imposing restrictions, because, as long as the essential freedoms are respected, the undesirable feature can be ripped out. you can use freedom 1 to adapt the program so that it does what you wish, and then freedom 0 to run it for any purpose. the undesirable feature may require you to modify the program before it does what you wish and serves you, but that's ok, you aren't entitled to expect others to write or share with you software that does what you wish. if you take software from them, it may bring hostile features, but as long as it's freedom-respecting, you can study it to see what it does, get help from others to make it do what you wish, and then run it at your service. I suspect you agree with this as well, and that we've miscommunicated again :-(
