It's important to remember here that Horvat got that exemption because of his YT audience, which the PGA clearly wants a piece of (as they should). But there's little benefit to Horvat, his sponsors, or the PGA if he can't, you know, do the thing that put him in this position in the first place. While it likely is an issue with the PGA's broadcast deal, they now have something to work toward in the future.
Regardless of what the old guard here thinks, the PGA needs YT more that successful YT golfers need the PGA. Between his content, sponsorships, brand deals, and ownership in Takomo and Primo, this kid is rolling in it doing what he loves (and without having to grind it out on tour), and he's smart to wait for a deal that benefits both sides.
This just shows a dramatic failure to understand the subject, at all.
