Problem with that is there may be other services that also leverage the same short code, meaning you may be blocking something you need in the future.

Edit: apparently according to Twilio:

Shared short codes are not permitted in the US and Canada or in most countries worldwide.

The only (very narrow) exception to the prohibition on shared short codes that is permitted by US/Canada carriers is a short code that sends OTP (one-time passwords) or authentication codes with strict adherence to a template, and no option for customization by the brands that are sharing the short code.

I’ve personally been messaged on a few different platforms saying that I can be a seller for marketplaces and make 2500+ USD a week. I assume that it’s these big companies that they’re talking around as to try and not spill the beans because I assume it’s below the line in some way.

For some people that may be pretty lucrative.

I think your bias may be showing. The average computer user doesn’t even think about using a password manager. It just exists and works in their browser.
