The NFL may have kept the price high but access to NFL ticket is now available to anyone who can stream which is just about everyone now. You don't have to even buy YouTube TV but you get a discount if you do. I don't know about any potential antitrust. Seems the league should be able to maximize their revenue for their product.
Still the cost is pretty high but for me in South Carolina it is the only way to watch the Rams and my 2nd team the Panthers which are not on my local channels because I am on the border of Georgia and only get Falcon games.
