What if someone buys one of the link shortner domains and redirects it to malware? Surely it’s almost impossible to change those links that are out there, for example on social media sites that don’t have an edit button.

@rythie Browsers could block the domain. Maybe if you needed to see where a particular link pointed, you could find it at archive.org, if you were lucky.
But yeah, don't use third-party link-shorteners. I guess a combination of Twitter improvements and QR codes have replaced the main use-cases for them anyway, which is good and bad; if they're largely abandoned then they're more at risk from malicious takeover.
