And over time society will recognise that prejudging applicants based on irrelevant crap unearthed on the Internet isn't the best business strategy, so the original problem diminishes.
Reality check. Look at the prevalence of tattoos. Think that the prejudice against that has diminished? As far as I can tell, it's gotten worse.
Before, tattoos were sufficiently rare that if somebody had one who was applying for a job where they were unusual, they generally were given the benefit of the doubt (ex-serviceman, gang member who got out, etc.).
Now, they're so common that they're used as a proxy for "lower socioeconomic status" and all the discrimination that comes with that.
