I understand this concern. The IPO initially worried me too, and no one knows how this will play out for XRP holders.
A few things to consider in my opinion are.
Ripple own the majority of XRP, therefore they have a clear interest in the future price, which would also help with the initial IPO evaluation and future stock value (40,000,000,000 XRP deemed as a company asset)
Ripple are expanding into more corridors utilising XRP
Ripple have met with the IMF and BIS on multiple occasions and demo'd RippleNet and the XRP digital asset

Trust and reputational damage
If Ripple decided to drop XRP then the work outlined above would be all for nothing. Most importantly they would damage their reputation, promoting a digital asset to the SEC, IMF, BIS, SBI Holdings, hosting Swell events etc and then stating "We no longer want to go down that route, we wish to utilise another digital asset or no digital assets at all and remain with xCurrent" would damage their reputation and question their credibility. It may also require modifications to the RippleNet implementation in order to remove any trace of XRP within the codebase (I am assuming this has been architectured in a loosely coupled manner where an asset would be interchangeable), however any amendments would include redeployment of software to existing clients infrastructure (Banks and exchanges) and full end to end testing to deal with a new digital asset, ensuring it works in the correct manner, as well as performing regression testing to ensure the software works as expected without XRP. This incurs additional business cost and introduces risk, if it went wrong it would make them look rather foolish.
It would also be terrible for the community if they dropped the XRP token, not to mention the amount of people who will believe they have been misled with Ripple's website stating where to buy the asset.
If they decided to go with another asset, who would even buy into it? Their reputation would be tarnished, no one would trust them and people would potentially try and raise a lawsuit against them, setting them back further within the digital asset space.
Overall, the Ripple IPO will most likely make a lot of the Ripple shareholders wealthy, this is just how business works. It is their duty to look after the shareholders who initially took a chance on them and provided investment, why shouldn't they be rewarded?
To answer the question "Do they give a damn". I would argue yes, from the points I mention above. Unfortunately they cannot just green light digital assets as it is outside of their control, Ripple have to be patient with regulations and work with the right people to ensure they understand the benefits of this technology and align with the policies that will be outlaid in the future. If anything comes of this is what we are all speculating on.
Overall the technology works, is efficient, secure, stable, scalable, provides a use case and helps solve real world problems with liquidity and cross border payments. Regulations are key to drive this forward and we must be patient.
