I'm just explaining to you how it plays out when a business is deciding whether or not to use TS at all. Mistakes and errors are checked for by linters and unit tests automatically in the background so that's not a benefit anyone cares about. The liability of having to find coders that want to work on your TS project decreases potential candidates and makes hiring more difficult. Large organizations can deal with it cause when you have 500 engineers on staff you can find 50 that will use TS for you. For smaller orgs it's a pain.
