$129 guarantees a commercial-free environment just as much as a $300/mo sky subscription. What a bargain!
I have TV's that've never had a live-TV feed, and have been used as "video" monitors or computer screens, so the device itself isn't the issue. However, the sky subscription, which at first was marketed in the basis of no adverts, now is a way to get paid-for channels that have more advertising than the fta channels, and I believe still as much "informercials" if not more (some 10+hrs/day of "informercials" on a non-shopping channel and people pay to have this shit in their homes? No wonder people are turning to alternatives...)
