Title kinda doesn't make sense to me, they argue to donate monthly instead of a lump sump which I can understand, a lot of individual artist / podcasters etc prefer this as well, because it's easier for them /Gnome to work / plan with a steady stream of income instead of random payments here and there.
Which I totally understand. But personally I'm not a fan of lots of small amounts cluttering up my (digital) bank statements every month, so I tend do just do "amount I'm comfortable to pay monthly x 12" once a year (sorry π¬).
