Yes, but the sports are the point of ESPN. If you had to describe ESPN to some time traveler from 1970, you would say "well its a TV channel that shows just sports." You wouldn't add "oh, and they fill the day with people arguing." Because the point of ESPN is the sports, they show the sports and between what you and the advertisers pay, the goal is to make a profit.
Here are the total viewers the BEST of the daytime arguers got in one report a few years ago (it is lower today):
PTI — 424,000
First Take — 316,000
Around the Horn — 269,000
NFL Live – 244,000
Highly Questionable — 214,000 (since cancelled)
The Jump — 198,000
Get Up — 178,000
Jalen & Jacoby —158,000 (since cancelled)
Undisputed — 153,000 (Fox)
The Herd — 100,000 (Fox)
They are paying these people MILLIONS of dollars. Millions. To entertain 200K people. Mostly shift workers, retirees, kids and people that don't work. (Not exactly your key demographic)
Yes, they pay a lot for the rights to the sports. They are worth it. These people just aren't.
