I like Plus overall, as FriendFeed 2.0 if nothing else. I hope they can fix these sorts of issues quickly.
That sort of seems like modifying FOSS and not bothering to contribute back your modifications to the original product because "from experience most FOSS projects don't bother about my code". (And yes, many FOSS licenses require you to provide your code if you distribute. They don't, however, actually compel you to actually submit it to the original project.)
In my eyes, it's about common courtesy: If you sign up for testing a product, you report your findings. That said, I'm not saying you have to, I'm just saying that by providing your feedback, specially when they actively are seeking it, you might help create a better product.
