By your definition any software you don’t like is bloatware.
A more appropriate working definition would be “software installed by a third party that you didn’t not ask for, nor will you likely use.”
Apple does not have third party apps installed on their phones when you purchase them.
That’s pretty much the universal definition of bloatware. Here’s straight out of Oxford:
unwanted software included on a new computer or mobile device by the manufacturer.
“users must initially contend with the usual bevy of bloatware (unnecessary toolbars, games of questionable value)”
Notice not 1 word about 3rd party. Look at Windows. Everybody’s #1 target for complaints about bloatware, and every single bit of bloat on Windows was written by MS.
