A meaningless few who watch professional wrestling do so for any reason other than their enjoyment of the scripted entertainment, the nature of which has always been at best implicit but obvious. The internet, the rise of wrestling media, and the corresponding increased visibility on the business side of these promotions make maintaining the illusion of the scripted storylines through secrecy more difficult, and the effect of attempting to maintain the illusion to such a point that they deny the scripted nature of the business rather pointless.
Therefore, recent years have seen major promotions recognize that selectively pulling back the curtain on the illusion further by referencing the business itself in a self-aware way allows them some control over that reality while also continuing to build narratives around the characters that the wrestlers and other talent play in these scripted shows. The heightened characters and broader scripted plots that connect matches remain motivating factors, at the expense of chipping away at the traditional concept of "kayfabe".
But why would viewers care about whether the champion will make a lot of money for the company given that the vast majority of viewers will not receive any of that money?
Because it's not about the money, it's about the conflict between the characters. Despite them talking about a real-world company, this still concerns the characters that the wrestlers are portraying.
Professional wrestling is by and large a scripted drama series about athletes, with scenes of interpersonal conflicts connected with stuntwork scenes of simulated competition.
What you're calling out is a plot point, even if it blurs lines with the real world. It's a storytelling property that modern wrestling employs, if not uniquely then distinctly; because the promotion knows that modern fans regularly argue over which wrestlers are most valuable to the promotion, the promotions use that to add heat to the character drama.
