You're definitely entitled to your opinion. My response is that a trial basis isn't two months. I see nothing in Wizard's posts that imply the Luny was a "trial." Of course, I may have missed something.
I'm sorry, but I just can't imagine having a dog for longer than a day and not falling in love and unwilling to do whatever it takes to work the dog into my family life. But then I've never had a dog on a "trial basis." I get a pet, I keep a pet, regardless of the pet's shortcomings. But that's just me. I take what I get and work with it, compromising on both sides 'til everybody's comfortable.
Once I get a pet, it's a family member, for good or worse. I'm sorry, I just can't fathom giving up a pet, unless severe aggression is involved, and I have, sadly, euthanized a dog because of severe aggression, years ago, for biting my son (twice), although, with all we know now, I would have been hopeful of finding a solution.
