It is possible, maybe, that we are missing the point here. The caretaker government asked Airports of Thailand, which has plenty of liquidity, to purchase bonds from them to help pay the farmers. AoT started to do so, but then some employees objected, so they stopped. It is most likely that the aim of these farmers is to "persude" AoT to purchase these bonds so that the farmers can get paid.

ปากกา Parker (any sort of pen)

I never associated ปากกา with Parker; I always thought this word came from ปาก and กา (as in a teapot's spout). ปากกา can also be spelled ปากไก่ and a quill pen is called ปากกาขนนก. Maybe you are right, but I imagine that there were pens in Thailand hundreds of years before the Parker company was formed and that Thais had already a name for the device. If it was indeed a case of a brand name adopted, I guess they would call it ปาร์เกอร์ rather than ปากกา.

Indeed, that sounds most likely. I've always assumed it came from "Parker" but now my illusions have been shattered! Parker Pens started in 1888 so I shall still cling to the faint possibility that the brand name was picked up once Thais moved on from the quill pen to a more modern type.
