One thing I would suspect is they leverage third parties and share your phone number to get back additional known data about you or your interests or other activities which other companies have shared. I think in a way it ends up being a connection point for your data across many places.
Obviously, never enter your real number in a web form unless the service depends on you getting called back … in which case you likely would have called the company by phone anyway.
Oh, i never experienced this. My thought is rather, “nobody will call anyway” … that said, perhaps it’s because i’m largely living outside of online buseness. Location: Europe mostly. What busenesses are you talking about, out of interest?

How do you combat this sort of thing? Besides periodically changing your phone number, of course

This is not possible.
Most services that require a phone number also verify it via sms.
Additionally they check so that each number can only be used once, disabling most free sms receivers online.

they’re talking about sites like Facebook or Google
Do you have any reason to believe this other than “corporations bad”?
Snowden for example
Also have you never heard of data brokers?
