We will never really know for sure what is behind the reasons people give or how honest or not they are being but in my opinion: why should we care about (and/or judge)their reasons? Sure it would be nice for people to "think" it through before getting an animal and be more committed to them, for life ideally, but the truth is circumstances/life/interest change. The important thing is they are taking responsibility for the pet and are looking for a new owner that has more time/interest in them. Nothing wrong with that.
I personally like handling mine a lot. Nearly daily. The length of time out depends to a degree on how they are that day. I let them "tell" me
for example my carpet starts exhaling when he has had enough, usually after about just 10 minutes! lol
