Breather hole in cylinder
(OP)
Can anyone tell me why a threaded hole with a breather plug is a better design than just simply drilling a tiny hole to allow air to escape in a high pressure cylinder? Would the smaller hole compress the air more and allow condensation to form?

you seem to be talking about something else "to allow air to escape in a high pressure cylinder?" but it is all very unclear. These are usually called vents.
Please provide more information (volumes, pressure, flows, diagram, picture etc) and a bit more explanation as to your question. I'm sure it's very clear in your mind and vision, but it's not in mine at the moment....
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

You can put things in the tapped hole that control motion and or noise, and keep the cylinder from inhaling and retaining crap.

Because it's a restrictive vent, it takes some of the slam out of pnuematic cylinder operation. The backpressure builds on the vented side as the piston nears it's end of travel. To some degree it slows to a stop instead of slamming to the end of travel, however you retain the full actuating force when the motion stops.
Of if you need to, in a pinch you could take out the return spring and make yourself a double acting cylinder.

How about this:
Breather Plug - A vent installed into a port on a hydraulic cylinder to allow a double-acting cylinder to be used in a single-acting application. http://www.baileyhydraulics.com/hydraulic-terms

For oil containers, hydraulic cylinders, and hydraulic systems
Hydraulic cylinders, which are intended to have a long service life must of course not be impaired in their function. For non-applied hydraulic cylinder spaces or oil tanks the danger exists that inflowing air may enable foreign bodies to enter the inside of hydraulic systems. These are indeed capable of causing major damage. http://www.haenchen-hydraulic.com/breather-vents-e...
