Those 3 points are valid but not even the worst bits. It sounds like you are just griping about the switching cost issues, and didn't get much further than initial setup. Once you actually try to use BW in earnest, you'll find it's noticeably worse than 1PW in most ways. The most glaring is that it is meh at detecting login forms and poor at detecting new account signup. These are the 2 primary flows for a pw manager…
I've used BW for years and have never had issues detecting forms.
I distinctly remember, the very first new login I created after moving over to BW. Nothing happened and I just assumed BW was simply not that chatty about such things. BW fails to detect a significant number of signups for me. It's not a rare occurrence. I've had to train myself to create the login explicitly, rather than hope for auto detection.
1PW has taken a wrong direction, so I "suffer" with BW. However I don't recommend it to anyone. (no one asks, so it's not much of a concern)
