I don't think TS should make a video on how to install Linux, because that's incredibly simple. Just by TS giving advice about Linux doesn't put anyone's computer in danger. TS would not be mandating that people install Linux on their machines so I don't see how it wouldn't be on a "voluntary basis."
i support linux by purchasing linux driven products.
Very nice, but everybody does, either directly or through tax money: phones, TV's, cars, washing machines, home automation devices, alarm systems, Wi-Fi routers, electronic musical instruments, airplanes, tablets, e-readers, bottle recycling machines, parking meters, weather stations, traffic control systems, trains, weapon systems, automatic defibrillators, medical imaging systems, data and application servers, gaming consoles, gambling machines, NAS units, managed UPS devices, internet infrastructure, cash dispensers, vending machines, manufacturing robots, scientific research equipment, space stations and satellites, etc... the list is endless. If Linux wouldn't exist, the world would pretty much go back to medieval times. Even the most die-hard linux-hating cyber-rednecks spend more money on Linux powered machines and services than on anything else.
