While I disagree strongly with GP, your argument seems to completely miss their point. GP expressed her opinion as to the utility/viability of Linux for their use case.
We both disagree with GP's arguments, but even we almost certainly don't share the same "set of preferences and pecadilloes."
Mostly, I think it's pretty closed-minded to denigrate someone who expresses an opinion (unrelated to facts presented in an objective reality).
Give the GP a break. If their "preferences and pecadilloes" don't match yours, why is that any skin off your nose? As such, why do you feel it necessary to belittle the opinion of some rando on the 'net?
I'll say it again just to make sure you understand that it's your tone and attitude that disturbs me and not the content of your argument: widespread use of package managers have completely changed Linux for the better IMHO. What's more, I find the arguments provided by GP to be both weak and unpersuasive.
