I actually had an installer start to remove a power strip - I call them power strips because they provide more outlets than surge protection.
Anyway, he said we couldn't plug PIs into power strips. Of course, there weren't enough outlets close by so I got him to leave the basement before he unplugged everything.
That is DirecTV's policy and I can understand why.
Now days everyone is pushing people hard to try to save electricity. One of the big things they try to tell people to do it turn off their power strips/surge protectors, or get the ones that automatically shut off power to most of the outlets when the TV is turned off. If the Power Inserter is plugged into a power strip and you turn it off, or it turns off automatically, that is going to kill the DirecTV signal to the entire house. Most people don't understand what the Power Inserter is there to do, so they end up calling in complaining that the system is broken etc.
They also usually like to plug the power inserter in behind your TV or dresser instead of other locations. They figure if it is plugged in back there you aren't as likely to move the TV/dresser and unplug it to plug in the vacuum, or Christmas tree lights, etc. and cause your system to stop working. If it is just plugged in where people can easily get to the outlet it is more likely to get unplugged.
If you know what the Power Inserter is for, and understand that it needs power at all times in order for your DirecTV system to work, then there is no reason not to plug one into a power strip. Actually, it is an even better idea to plug it into a UPS (along with your DVRs) so that short power outages etc. don't interrupt your recordings.

Sometimes when I reflect back on all the beer I drink I feel ashamed. Then I look into the glass and think about the workers in the brewery and all of their hopes and dreams. If I didn’t drink this beer, they might be out of work and their dreams would be shattered. Then I say to myself, "It is better that I drink this beer and let their dreams come true than be selfish and worry about my liver."
