On Hearthside, it is illegal to use terms such as “buy” or “purchase” (rather their Hearthsider equivalents) unless a transfer of ownership is taking place. If you're paying for time-limited access (even if that time limit is measured in centuries) terms such as “hire” or “lease” must be used. Moonlitter has similar laws, but the AW differs depending on jurisdiction.
The Pious Dissolutionists pioneered (or at least championed) what humans would call “open source”, thanks to the treaties following the war of dissolution banning the Bright Way from selling their tech. Research monasteries can sell the patent rights to something, but can't monetize access to such products. When the mass router is invented, they can either sell the patent to another entity for a one-time fee or open source it, allowing anyone to manufacture it royalty free. Because the culture of the Pious Dissolutionists tends toward anti-corporatism, they almost always make the tech available to all.
