Interesting! I think there's a tangible difference between "you may only use this product if you support/disavow $x" (as in, some public statement of views is a prerequisite to being allowed to use something) and "you may only use this product if you do not cause harm in some tangible sense".
While I'm not necessarily saying I agree with either, the first is certainly less reasonable than the second (and the two examples linked are of the second kind).
> So you need to have a secure method of communication to transfer the code? Then why not just use whatever that is to transfer stuff?
Because sometimes that secure method of communication is speech. This is a particularly good utility for transferring information to parties that you can talk to verbally. Also, a bit quicker than plugging a USB stick in.
Partial functions are not the same thing as "partially applied functions". Partial functions means that not every element of the domain is mapped to an element of the range, for example:
divTenBy :: Double -> Double
divTenBy n = 10 / n
If you actually call the above function you get a runtime exception. We really don't like functions that do this; they are called partial.
A big benefit, especially with more people, is that it's relatively painless and socially natural to break out into multiple small discussions (as might happen at say, a coffee meeting irl). The awkwardness of 12-person video calls is extremely painful in other software.
