This doesn't mean we shouldn't ask for Apple to do better, or try to get changes made. But, I do think it's completely ridiculous to rage about repair-ability like the parent did.
What would obviously be even better than anecdotes is some statistical data on the likelihood of failure, average cost & convenience of repairs etc. I don't know if such a thing exists - in its absence we have to make do with anecdotes.
I think sharing stories is fine, but the poster seemed to be going much further than that by seemingly trying to get revenge on Apple, which is a strange thing to do.
Statistical ownership data would be awesome. Like a graph saying that if you expect the device to last x years you should expect y costs in repairs. That could even be a selling point for tech protection plans like Apple Care.
Even if two thirds of the price of the laptop is a reasonable reflection of the cost of repair, poor repairability is a choice Apple made. It seems fair to criticise the cost, and to factor it in to future buying decisions.
