I wonder if it's down to people using online genealogy sites differently than they might have done originally.
For example, 10 or more years ago, someone seriously into family history might have only posted a tree that had been proven to whatever level of satisfaction fulfilled his or her purpose.
Genealogy used to be more costly, more difficult and more time-consuming, perhaps thereby limiting its attractiveness to some. Remember how patient you used to have to be if you were writing letters and waiting for replies from other countries?
But now the vast amount of information available online, and the ease with which it can be added to one's tree, has perhaps contributed to lowering the former standards of proof while at the same time making it much easier to engage in the hobby.
In addition, people use the internet now as their storage and back-up for working documents, photos, etc., so it probably makes sense to many to also use the internet for their trees, whether they are works in progress or as complete as they can be. I have a cousin whose tree exists only on Ancestry; I'd be surprised if she has any kind of genealogy software or data stored on her computer's hard drive. She keeps hers private but others obviously don't.
In the end, it doesn't matter. I agree that it can be annoying or downright ridiculous, but not everyone is a stickler for detail like me, and so I just shrug my shoulders and scroll on.
On the other hand, I am extremely grateful to the individuals who are meticulous and who go to the trouble of attaching source documents or links to back up their data. Yes, it can be a pain in the butt to scroll through the 17 (or 37) trees whose owners have merely copied and pasted some or all of the meticulous person's tree, but there's a definite pay-off if I can make my way to the original, well-sourced tree (when one actually exists).
On the lighter side, I recently started updating one of my family binders, with the intention of creating one for my brother and his children. Well, that got me back to researching that line, I've found a ton of new info, and am still in the process of gathering and synthesizing it all. So the binders are on hold again.
