Given the general move to 2024 content and the nuisance involved with some of the references, such as the wrong Grappling rules being listed on sheets, is there any possibility that those of us who purchased 2014 content can be given pdfs of the product we paid for?  I'd like to see and use what I purchased.  I'd happily accept pdfs with a watermark of my username if piracy is a concern.

The digital book (compendium) is unchanged. A PDF is not necessary. You can view the book with or without a character sheet. You can download a copy to a device using the D&D Beyond app for offline reading if desired.

The tool itself is being updated to the 2024 ruleset which is the new standard. This is not the same thing as the book - which you retain access to and lists the original rules as detailed in the physical book.
