Individually and through Liberty political action committees, Malone and Maffei collectively gave $1 million to Trump’s 58th Presidential Inaugural Committee, according to Federal Election Commission filings. The donation follows roughly $1 million each to conservative national candidates for office, FEC records show.

Trump’ inaugural committee and a related super PAC are the subject of federal investigation for influence peddling and illegal coordination. Donors of $1 million or more, according to a brochure published by the Center for Public Integrity, received four tickets to a “leadership luncheon” advertised as an “exclusive inaugural event.”

Liberty spokespeople didn't respond to comment requests from KQED. In interviews, Malone has voiced his support for Trump's positions on trade and immigration, and said he expects the administration to be favorable to the entertainment industry.

Although Liberty’s controlling interest in Sirius has received little media attention, the Pandora acquisition comes at a time when conservative music industry giving has prompted protest. 2017 reports of Philip Anschutz, Goldenvoice parent company AEG’s owner, financially supporting anti-gay organizations spurred calls to boycott Goldenvoice music festival Coachella. (Anschutz called the stories, based on public records of his charity, “fake news.”)

Liberty connections to Trump aside, Sirius has attracted liberal criticism for its own programming decisions. In 2016, a media coalition protested Sirius' move to eliminate 80 percent of its Latin music channels, saying the satellite service turned its back on Spanish-speaking listeners “at a time when Latinos are most misunderstood and fighting constant attacks.”

The next year, Sirius reintroduced Steve Bannon as a regular host on its Patriot channel, calling the former Trump advisor a “conservative populist icon” as part of a Breitbart expansion. In response, celebrities such as Seth Rogen and Melissa Etheridge called for a boycott of Sirius. “I will not be a part of normalizing hate speech,” Etheridge said at the time.

(Breitbart eventually cut ties with Bannon in 2018, forcing him to also step down from Sirius.)

Liberty is also a partial 34-percent owner of Live Nation, the world’s largest concert promoter, where Maffei also chairs the board. So the Pandora acquisition is, however indirectly, an expansion of Live Nation’s presence in the Bay Area. Goldenvoice and Live Nation have aggressively angled for more control of the local concert market in recent years—to the detriment, critics say, of show-goers and independent venues.

Though the relationship between Pandora and other Liberty holdings such as Live Nation remains to be seen, Pandora cofounder and on-and-off executive Tim Westergren approvingly cited Sirius’s connection to “the live business” last year. And Liberty plans to expand further in the music business: According to a recent feature in Rolling Stone, it's even eyeing broadcast giant iHeart Media.

Sirius XM is itself the result of onetime competitors Sirius and XM merging despite antitrust concerns in 2008. Kevin Erickson, director of Washington, D.C. artist advocacy group the Future of Music Coalition, said the Pandora-Sirius deal continues a troubling consolidation trend.

“If one company is allowed to combine the satellite radio monopoly with the largest company in digital radio, the largest broadcast radio station group, and potentially one of the two dominant forces in live music, that's truly unprecedented gatekeeper power,” Erickson said, calling the plan “a catastrophe for independent musicians and a fans.”

As so called non-interactive services, Sirius and Pandora rely on statutory licenses issued by the government as a baseline for their royalty obligations to artists and copyright holders. Without competition, Erickson said, that baseline becomes the ceiling instead of the floor. “When one buyer effectively controls an entire marketplace—what’s called a monopsony—they have the bargaining power to drive wages down,” he said.

As an example of Liberty’s artist relations, Erickson pointed to the Music Modernization Act. The legislation, signed into law last year, aimed to adapt copyright for the streaming era in part by extending federal copyright protection to sound recordings made before February 15, 1972. Liberty, according to Erickson, was the act’s most aggressive opponent.

“So we already know something about how much respect they have for musicians,” he said.

Meanwhile, Bay Area tech industry ties to the Trump administration have begun to draw the ire of rank-and-file workers. Last June, protesters disrupted Salesforce’s annual Dreamforce conference to decry the software company’s contract with U.S. Customs and Border Patrol. The Tech Workers Coalition has argued that the contract makes Salesforce complicit in Trump’s anti-immigrant campaign, despite the company's outspoken liberal leader Marc Benioff.

The mood among Pandora employees towards Liberty’s little-publicized political affinities is unclear. Two workers who asked to remain anonymous told KQED office talk is focused on the company’s move last year to cut 5 percent of its workforce amid an expansion in Atlanta. The combined company, according to an internal document reported in October, will be headquartered in New York.

Pandora had 2,488 full-time workers worldwide as of late last year.
