My reason for boycotting Ryanair is philosophical, rather than the practical considerations you mention and I'm sure I'm not alone. The few times I flew them I had no particular complaints. But at one point, after one more obnoxious attempt to get our attention by the CEO, I resolved that if Ryanair was the only way to get somewhere, I just wouldn't go there. I can only elaborate by comparing my feelings about the airline to those regarding some hotels. Under no circumstances would I stay in a Trump hotel, even if it was free. I suspect my stance is the same as many others, having nothing to do with good service or the hard-working people who provide it.
