It's probably worth distinguishing 'bloatware' from 'crapware', even if Wikipedia does consider them synonyms.
Roughly, I'd say that bloatware is anything preinstalled that's not filling a core use-case for the device, plus literally anything unremovable that isn't part of core functionality. So Messages isn't bloatware, but Messages+ and Samsung Health are. The first standard is sort of a fuzzy with general-purpose devices like computers and tablets, the second is pretty clearcut.
Crapware, to my mind, is "bloatware + shovelware". It's preinstalled stuff that's broken, malicious, redundant, or outside of standard use. Samsung Gallery is crappy, Superfish was malicious, VZ Navigator is basically a scam (paid, bad Google Maps), and the NFL app is worthless to a huge fraction of users.
The Office suite is very popular and highly functional, so I'd give it a pass if it could be uninstalled. Since it can't, it's bloatware. OneDrive is on the line; it's a popular complement to Office, but it's vendor-specific in a way that opening documents isn't. (Low-impact is not at all a defense; the 'disabled' state is nice for quick reinstalls, but there's no user-friendly argument for not allowing deletion.)
LinkedIn is absolutely crapware of the worst kind. It can't be uninstalled. It's irrelevant to a huge fraction of users (anyone who doesn't work). Its provided for the benefit of one company in a crowded space, whereas Office is a clear market leader. It's redundant functionality with a simple website, where Office is only partially duplicated by OpenOffice and Google Drive.
And worst of all? It actively hurts users. When LinkedIn lost its user data in 2012, the breach was made substantially worse because their iOs app scraped and uploader user data (including calendar info!) without permission. Permanently preinstalling an app that's largely useless and has already contributed to a major data breach is far outside what I consider acceptable behavior.
