Common Dreams article details the response to a CNBC piece about a PAC partially funded by Musk is collecting specific user data. CNBC states (archive):

[…] users who enter a ZIP code that indicates they live in a battleground state, like Pennsylvania or Georgia, the process is very different.

Rather than be directed to their state’s voter registration page, they instead are directed to a highly detailed personal information form, prompted to enter their address, cellphone number and age.

So that person who wanted help registering to vote? In the end, they got no help at all registering. But they did hand over priceless personal data to a political operation.

“What makes America PAC more unique: it is a billionaire-backed super PAC focused on door-to-door canvassing, which it can conduct in coordination with a presidential campaign,” Fischer said. “Thanks to a recent FEC advisory opinion, America PAC may legally coordinate its canvassing activities with the Trump campaign — meaning, among other things, that the Trump campaign may provide America PAC with the literature and scripts to make sure their efforts are consistent.”

The America PAC raised more than $8 million between April 1 and June 30, according to FEC records. It has received donations from veteran investor Doug Leone, cryptocurrency investors Cameron and Tyler Winklevoss, and a company run by longtime venture capitalist Joe Lonsdale, according to FEC records.

They also quote the NYT in saying Lonsdale is one of Musk’s political confidants – which is interesting because he’s at Palantir which was you’d think of as his old buddy Peter Theil’s gig. Palantir sells info. More precisely, they know how to intake truthful data and turn it into actionable details. I’ve no idea how they check for validity, though. Some days it feels like everything on Twitter is a lie and hearing that this ‘help you vote’ program is also a lie just makes me wonder if anyone is honest over there.

Common Dreams quotes several angry reactions to the CNBC article, such as:

Former Congresswoman Marie Newman (D-Ill.) took aim at Musk, saying, “If you did not believe he was maniacal or evil, before this, well now you know.”

They also note that:

Last month, Sen. Bernie Sanders (I-Vt.) publicly thanked Musk for doing “an exceptional job of demonstrating a point that we have made for years—and that is the fact we live in an oligarchic society in which billionaires dominate not only our economic life and the information we consume, but our politics as well.”
