Am I the only one who thinks canned air is bad for most camera shutters?

I keep seeing people recommend blasting dust out of shutters with canned air and it drives me crazy. Last year I had a Nikon F2 come in with a shutter that was sticking at 1/1000. The guy said he used canned air to clean it. When I opened it up, there was condensation residue from the propellant all over the curtain blades. Canned air shoots liquid if you tilt it even a little, and that liquid eats away at the lubricants on the pivots. I've fixed 4 shutters in the last 6 months that had the same issue. Use a proper bulb blower or a compressor with a moisture trap. How many of you have seen damage from canned air in your shops?

Buddy of mine melted his shutter curtains the exact same way.

Totally disagree, @kevin_martin, my curtains are fine after the same thing.
