This is a good reason to use a service like Burner ( https://www.burnerapp.com/ ), and also probably to cycle your GSM handset number at your carrier multiple times per year, as TFA notes. (Switch to TOTP or U2F for two factor.)
I already use anonymous single-use email addresses for a lot of services (anonaddy.com is good for this), and I think in the future I'm going to just decline to use anything that demands a phone number of me. Far, far too much of it is being sold to third parties as soon as it's obtained by these companies.
Ironic that the service that's supposed to protect my privacy redirects me to a tracker (adjust.io) when trying to download their app. I'm also willing to bet good money the app itself will have creepy tracking built-in.
