It's still an invasion of privacy, and Intel has no business knowing I play (and how much), e.g., a gay dating simulator, Postal, Hogwarts Legacy, or any number of other games that either are or will be controversial, incriminating, or just useful as another data point in a personality profile.
So many of the devil's advocate posts justify it by explaining how spying on users can be useful. But the complaint isn't that it's "not useful"!
For example, Texas Attorney General, Ken Paxton, attempted to secure a list of every Texan who changed their gender within the past 24 months, stating they may need drivers license numbers in the future to look up their information. The only reason that didn't happen is because the Department of Public Safety said they couldn't accurately produce that information.
Just imagine a state, or a foreign government subpoenaing or hacking Nvidia to get this information they're collecting. Now that state or foreign government doesn't just have your browser history like if they subpoenaed your ISP. They have everything you did on that computer. What's on your hard drive, what games you played, what devices are connected to your computer, etc.
I try to not go down the slippery slope analogies, but a company having this treasure trove of information on 82% of desktop users is going to make it ripe for hacking and state-sanctioned spying.
