This would cost spammers and bots way more money than emails. Perhaps it's due to the fact that they won't be able to use the phone number to send their spam (or they could I guess, but it would cost them some money). |
CAPTCHAs also can be unreliable with false positives and false negatives and other problems (although some CAPTCHAs are worse than others). "CAPTCHAs are trivially defeated today, regardless of the provider" is just one more thing, that makes even more worthless.

Even telephone numbers you might not have, or might be shared with someone else (more likely to have shared telephone numbers than with email).
