During the initial connection, we have to “pick a winner” and determine which of the 2 cells’ values to use. The logic is that the empty cell will be overridden. If both cells have values, the direction of how you connect them determines the winner. Dragging A to B will have B’s value overridden by A’s value.
However, the developer of the module, or the creator have the ability to specify the direction flow when necessary. For example, in the Github example, the Github module populates the (issues) cell via fetch call and is expected to be a read-only cell. This means that any connection to the cell will become a directional data flow out.
The simple big picture is that we are drawing lines to tell the system how we want data to flow among the different modules, very much like how we pass variables around in code.
Because they have duty to do so, as (part) owners of those companies. They could face personal liability for being negligent enough. You'd think any company with non-trivial payroll should've known better than not to hedge on all the things, including their banking partner.
This is not a forum for PaulG, DHH and others to rant against companies on, yet it seems to be more and more the case nowadays.
If there's an article with actual content that should be posted and discussed here, not a Tweet.

And I should say, it's not even necessarily about politics. I'm not a huge sports fan, and in the same way, I would like to be able to unfollow posts about sports, etc of friends on Facebook.
