First off, the bigger tech companies are already known for having much higher salaries/compensation, hence the whole FAANG goal that many applicants aim for.
Generally, people have an incentive to pick a startup vs a big tech company for several reasons, such as preferring the startup work environment, the fact that their equity has the potential to grow in value much faster than equity at an established tech company, etc.
On top of all that, even with big tech paying the biggest salaries and attracting talent, they still have a finite number of positions. All the applicants who aren't FAANG level will go to work for those other companies that don't pay as high.
Adding transparency to job posting salaries is a net benefit.
