For our product, 2FA is pretty important as a security feature (domain registrar). That said, if you don't want to use it, that's on you as the user. We help out in a different way for those users - we make it impossible to disable account sign in email notifications if you don't use 2FA and those email notifications include a "nuke all active sessions and lock my account" button that can (and has) saved users if their account is compromised due to things like leaks of credentials that they've reused on multiple sites.

2FA is a major hassle for support when users get locked out because they smash their phone or change phone numbers or somehow lose access to the 2FA method. But, the benefits of 2FA largely outweigh those downsides for the majority of users. Offering the choice though, is something we think is important.
